what is this

It's NOT a fuselage (69-71) C-body and I think the subframe on those is the same as 65-68 (or so). It's also late enough that it has bolts for alignment instead of cam-bolts. The center link is an oddball, too. The only reason I am willing to assume Mopar is the torsion bars. It's also NOT from an F/M/J/ etc late model RWD Mopar.
