We chose to work with Pete & Jake’s Hot Rod Parts of Peculiar, MO to supply us with a mixture of vintage and modern components for our project. Our frame is fully boxed and welded on a jig to match our existing body mounts. Additionally, we chose to keep the solid front axle design but with a twist: it is now mounted via “hairpin-style” radius rods instead of the stock “wishbone” design. We replaced the original hydraulic shocks with modern, gas filled units that will help soak up any rough roads.
We updated the steering system, too. The relocated, modern steering box and cross-steering linkage will greatly reduce bump-steer, a drawback of the original push/pull design. Mounted to our new front axle are hydraulic disc brakes that replace the original mechanically actuated drum brakes. The original mechanical drum brakes were an effective design for the time, but advances in braking technology make a swap to hydraulic brakes a wise decision. To actuate the hydraulic brakes, we opted for a dual circuit master cylinder mounted along the driver side frame rail. This was necessary due to relatively scarce space available on a Model A firewall.
Moving to the rear a new Ford 9-inch rear axle is mounted to the frame via a ladder bar setup. This replaces the original banjo rear axle and torque tube assembly. To further simplify the assembly we chose to eliminate the single leaf spring and instead utilize a coil-over shock setup. Standard Ford hydraulic 11” drum brakes take care of stopping the rear wheels without looking out of place. And to make the car easy on gas and highway friendly we opted for a 3.00:1 rear axle ratio.
Together these updated systems will give the Model A the feel of a car almost half a century its junior. Of course the goal here isn’t a “corner carving” track day terror, but an “easy to drive” classic. We think this package is going to deliver that experience for the young owners.
