Vince is right about the HAMB (https://www.jalopyjournal.com/forum/threads/driving-the-kookie-kar-back-to-1958.1110832/) article. Just about everything you need to see is there.
Here is where I am on sourcing parts for my build.
From the Outlaw kit: I took the Cadillac engine (Trans and carbs I'll use from the Tweedy Pie kit) and full exhaust, tube front axle and radius rods, front chrome shocks, rear cross member, rear chrome shocks, rear spring, steering arm and windshield supports..
Baby moon hubcaps from an AMT '57 Ford.
Supported headlights and lenses from an AMT 1925 Model T Ford double kit.
The rest I will try to use Tweedy Pie parts and change them if needed.
Well, now to start on modifying the Tweedy Pie frame.
Good luck on your build.
