Got a rear end from a friend he thought it was for a mustang but turns out prolly from a Explorer or something...it is identical to my old rear end except for it was missing the quad shock brackets which i took both rear ends down to the local welding shop had them cut off the brackets and put them on the new rear end.The only problem now is that that yolk is bigger on the new rear end so i will probably have to switch yolks never done this before, is there anything that i need to know besides pulling that nut off and switching the yolks around your help is greatly appreciated .
