this really should be 2 questions, i never can get the search deal to help me out for what im looking for.... is there a " search help/ how to use properly " page ?? anyway .... my real question is , my friend is trying to sell me a front dana 60 out of a chysler ... best i can tell the perch mounts are slightly different in width... will it work? he said we can move the one to make it the same but is that right?? and if so will it be centered under the truck? I would imagine this has been covered but -- any thoughts would be appreciated.
