difference in F-1 frames ??
 

I am trying to put together a 51 F-1 pickup truck, I noticed thst there is A 46 f-1 frame which is available. Is this basically the same as the 51 without a lot of fit up ?? If not does someone have a 51-52 f-1 frame available in say the connecticut area or close to it ?? Tom

Basically yes but the 42 to 47 has a boxed section for the cross steer steering box, the 48 changed to drag link style .
Pre 48 was set up for lever action shocks.

You will be drilling out rivits and adding bolt holes.
