1972 chev 4x4 on blazer frame
 

I came across a 72 blazer frame with a pickup A/C cab and short bed mounted on it. They had to extend the frame 11 inches. It is gusseted on the inside and looks like it was done professionally. The cab has been entirely redone and has great wheels and tires. the bed needs some body work. Newly overhauled motor.

Will this setup work?
OR should I be afraid of it.

Any advise?

That has been done before with success. You might want to have a frame shop take a look at it and give you a professional opinion on the frame work that was done.
