56 chevy truck project

hey guys i was wondering if you could help me out a little bit. I was wondering if the cab and also possibly the fenders of a 56 chevy 1 ton truck are the same size as the regular 56 half ton truck. Also if anyone has done the swap info would be great.

Thanks in advance

 

cab same fender not

 

1 ton fenders are the same. 1-1/2 ton are different.

1 ton is model 3800. 1-1/2 is model 4000 something.
