Red Headed Stepchild-75 Swinger LSX Swap

Well it warmed up a little more and my Chief's exam is over with so back to the Dart it is. Started on the rear today, gotta admit that this 40 year old suspension gave me hell in the back. Ended up breaking all 4 of the nuts off trying to get the lower shock mount plate loose, but she ended up finally giving way and then I dropped the rear air shock down too. Also snapped the two bolts on the rear shackle on the drivers side too, so gotta order some of those now. Nothing I didn't kind of half expect this ancient, never been taken apart before suspension to do(with the exception of the shocks). Here is a little side by side of the old and new.
