I just found a 50's Ford truck frame, with straight axle, rear-end, pretty much all complete, but stripped, and on blocks. The cab was sitting about 10 feet away, not on blocks.
Still, there is still enough aftermarket parts to convert this over to better brakes, and make a good chassis to put a fenderless body on.
Which, pretty much solves the two problems i've always had with building fenderless cars. Straight Axles, and front brakes.
