triangular four link & 72 firebird sub frame on a 56 chevy truck

[coody]

any thoughts on installing the triangular four link & sub frame under the 56 Chevy truck. I have a disc brake rear end out of a 09 ish Camaro. Its 65" wide. The old six lug is 62". the four link will give me clearance to bring the wheel closer to the frame. I believe this will work. Up front I seen the sub frame welded straight to the frame & under the frame both make it sit low. Any thoughts & ideals on this? thanks!!
