My wife found a 1929 model AA truck that followed us home. After shoring up the frame rails with temporary cross members, I knocked off all the brackets that I knew we wouldn't be using. Also the front crossmember was loosely bolted in. I bought a 32 front crossmember to weld into my (her) newly boxed in frame. It looks as if the caster angle is built into the aftermarket crossmember. My question is if the frame rails are the same on both vehicles? We are turning into a 1/2 ton truck as opposed the 1.5 ton that is was originally. Thanks in advance!
