Hey FlyFish,the exact same thing happened to me(perches moving)I got them rewelded on(using wet rag for cooling)A couple months later I pulled an axel to check splines for twisting(again)Yes the splines were twisted again.:banghead:I already had plans for peicing together a Dana 60.Upon removal of my narrowed 8 3/4 I noticed the driver,s side perch collappsing and the housing twisting(no brace).So I put my narrowed Dana in with the mono,s/Caltracs.I also decided to improve my driveshaft to a chromemoly one with the 1350 u-joints and 904 yoke(Mancini,s)She,s bullit proof now.Maybe you can find another housing and brace it?Mine was a C-body rear narrowed that I paid $100 complete with .489 case and 2.76,s.Couple pics of damaged rear..
