suspension swap

[Nate]

Hey all, i bought a couple of 72 521's from a fellow member on here. One of them is in good "stock" shape (truck A) but does not have a motor or trans and the other looks like hell (truck B) but is lowered and has a good running motor and trans. My hope is to make one good one from the two (A+B= a good one). I really like the way the truck B sits so i would like to swap the suspension from truck B to truck A. So from the threads ive read, i know i can just swap the rear leafs, blocks and shocks from truck B to truck A, but can i simply swap the tornsion bars from truck B to truck A and get the same stance in front???? If this is possible can someone give some step by step for the 521 torsion bars. Ive seen some write ups in here but they are 620's. Any suggestions or advice would be greatly appriciated.
