advice??
 

hey guys.. i am doing the same thing with a 72 chevy.. i have a 4x4 frame all blasted and apart... i also have a 72 chevy 4x2 i just bought from a board member. that frame looks very clean and the body is already on it.. It is a coil all around truck.. what will be easier and fastest to do.. i need help thanks

I guess you are trying to make a 4x4? You are on the right track with the new frame.
Don't even think about changing the 2x4 frame over. They are really different.

Good luck

Swap the body onto the 4x4 frame. It's a direct bolt on but make sure you use the 4x4 body mounts as they are different.
