Dressing Up a Chassis With an Art Morrison Enterprises Bikini Clip
I

t’s been fascinating to witness the changes that have taken place in hot rodding over the years—most notably the inclusion of cars that at one time would not have been considered to be raw material to build a legitimate hot rod. While the foundation of the hobby was based on cars of the ’40s and earlier, the interest in vehicles produced during the ’50s and ’60s continues to grow—and some of the coolest of them all are station wagons. A case in point is Colin and Sue Radford’s ’57 Ford Del Rio Ranch Wagon.

Two-door wagons, like the Radfords’ long roof, can be cool cruisers and utilitarian to boot. What a great way to haul family and friends to a show, a swap meet, or just go for a cruise. But while cars of this era are arguably better drivers than their earlier counterparts, they can certainly benefit from upgrades. Typically these cars can use improvements in the suspension department—standard steering can require the arm strength of Popeye to turn a corner, not to mention parking, and the power steering of the day was usually over-assisted, vague, and prone to leaking from a variety of hoses. Brakes are generally not what you want to rely on in a panic stop and the front suspension geometry wasn’t designed with spirited driving in mind.

Colin Radford prepares to give the family’s ’57 Ford station wagon contemporary ride and handling capabilities with an Art Morrison Enterprises (AME) Bikini Clip. That’s his completely homebuilt, Flathead-powered T roadster sharing shop space.
When it came time to update the front suspension under the Radfords’ wagon, there was a decision to be made. The original suspension could have been updated with contemporary steering and brakes, but then the same old frontend geometry would remain. And when the cost of rebuilding the original suspension was factored in that option lost its appeal. An entirely new frame could be slid in place, but that was outside the allotted budget. The most sensible option from a cost and performance standpoint was an Art Morrison Enterprises (AME) Bikini Clip grafted onto the original ’57 frame, so that was the option chosen.

AME’s Bikini Clips uses the same proven suspension geometry found in their complete frames (several performance levels are available) and include custom tubular control arms with either coilovers or air suspension. To ensure accuracy caster adjustments are made with shims rather that the common Mustang II–style slotted holes that can slip. To customize installations AME offers stock or 2-inch drop Wilwood spindles, and a variety of Wilwood brakes are available. All those cool suspension parts are attached to subframes made from 2×4-inch rectangular tubing in either 0.120- or 0.180-inch wall thickness (ours is 0.120). A beautifully formed, mandrel-bent center crossmember anchors the lower control arms and mounts the rack-and-pinion steering.

Like most other IFS assemblies, careful planning, precise measuring, and quality welds are required to install an AME Bikini Clip. Colin has years of fabrication experience and is a certified welder, however others may want to seek help from a professional. Regardless of how it’s done, results will be well worth it. Besides, who doesn’t love a bikini?

The AME Bikini Clip will provide ride and handling qualities that couldn’t be imagined in 1957. We added a Flaming River power rack-and-pinion and suspension will be via coilovers.

Goodbye To Our Friend:
We would be remiss if we didn’t pay tribute to our friend, Craig Morrison, Vice President of Art Morrison Enterprises. Craig died on June 13, 2021.

After graduating from business school Craig eventually joined his father at Art Morrison Enterprises. He started by sweeping floors, worked in each and every department in the company, eventually rising through the ranks to become VP, dealing with marketing while creating a number of new products. Craig could often be found at street rod events working in the AME booth; he would be one of the guys who was always upbeat and smiling, the other guy would be his father, Art. In the Morrison’s case, the acorn certainly didn’t fall far from the tree. They truly enjoyed each other at work and play and it showed.

Craig was a many-faceted individual. He was well known as an automotive enthusiast, outdoorsman, and businessman. He was a force in the hot rod industry, his wit and sense of humor were legendary, and he made friends easily. But more than anything Craig was a devoted son, husband, and father. Our condolences to parents Art and Jeanette, wife Clarey, and son Alexander, and to his legion of friends. Craig will be missed. —Ron Ceridono.

Colin found the stock frame sloped up front to rear making determining ride height difficult
1. AME recommends having the chassis at ride height when attaching their clip. Colin found the stock frame sloped up front to rear making determining ride height difficult.
Colin leveled the body according to the driprails.
2. As the wagon was going to have only a slight rake, Colin leveled the body according to the driprails. The important factor is to ensure the new clip is level to maintain the caster that is built into the suspension.
The framerails of AME’s Bikini Clip are long enough on both ends to allow trimming
3. The framerails of AME’s Bikini Clip are long enough on both ends to allow trimming. Ride height can be varied by where the new ’rails are grafted on the original chassis.
the wagon was leveled
4. Before the stock suspension was cut off the wagon was leveled, then the chassis centerline was established with a plumb bob.
Masking tape was used to make easily identifiable reference points on the shop floor.

Here the centerline of the original front crossmember is established.
6. The key to success when installing a clip is to take a variety of measurements. Here the centerline of the original front crossmember is established. Note the hoses for the ram on the original link-style power steering (surprisingly, this one wasn’t leaking).
accurately locate the centerline of the spindles
7. A critical step is to accurately locate the centerline of the spindles. Of course the wheels have to be straight to do this, so the center of the hubs were marked (this was double checked with the grease caps removed).
For accuracy the suspension was compressed to ride height with threaded rod that replaced the shocks.
8. With help from grandson Tate, the centerline of both front wheels was verified from the front of the original frame. For accuracy the suspension was compressed to ride height with threaded rod that replaced the shocks.
The spindle centerline was also checked by measuring to the rear at the body mount.
9. You can’t take too many measurements. The spindle centerline was also checked by measuring to the rear at the body mount.
Satisfied that all the measurements were accurate, a plumb bob was again used to make reference marks on the floor.
10. Satisfied that all the measurements were accurate, a plumb bob was again used to make reference marks on the floor.
As some fabrication of the front bumper mounting points will be required, measurements were taken from the ground up and the spindle centerline forward for reference
11. As some fabrication of the front bumper mounting points will be required, measurements were taken from the ground up and the spindle centerline forward for reference (we will show how that was done in the next installment).
Two main factors dictated where the frame was to be cut. The first was the location of the spindle centerline. The cut was made 16-1/2 inches back from that point.

The second factor determining where to make the cut was where the subframe and original ’rails would best blend together, so a horizontal cut was made in the Ford’s frame.

The severed portion of the wagon’s original frame was hoisted up and away.
14. Talk about the point of no return, here it is. The severed portion of the wagon’s original frame was hoisted up and away. In some applications the front portion of the frame could be salvaged for bumper and core support mounts—not so in this case.
The Ford’s framerails were approximately the same gauge steel as the AME bikini clip.
15. Here are the initial cuts made in the frame. The Ford’s framerails were approximately the same gauge steel as the AME bikini clip.
The edges of the cuts were cleaned up with a grinder, being careful to maintain the measurements that had been established.
