"there is a 8 3/4" rear complete with new brakes and 3rd member local to me for $100 and a 2.93 sure grip center section also local to me for $175 and have it narrowed and rebuilt by a local shop"
That sounds like a good deal to me! But, I'll bet you can still put an 8.25" from an Aspen/Volare (plenty strong) in there, for half that... and already have BBP axles and the right gear...
