Not sure if this goes in tech or talk..it is tech but just really asking a question. Anyway, do any of you fine Mustang enthusiasts know of a company that sells "built" rearends? By the time I buy the gears, Auburn Pro dif, 31-spline axles, heavy duty dif. cover and a rebuild kit PLUS pay somone to do the work for me I am looking at a good chunk of change. I do not know how to do all this work by myself. If I could just purchase a complete rearend already built though I would have no problem swapping them out on my own. I have replaced all the rear suspension stuff (UCA's/LCA's/springs/shocks/driveshaft/and added adj. rear swaybar) so I know what all it takes to drop a rearend. I just have no clue about the internals of it. I have a manual and magazine articles on it but it still looks like Chinese to me. Plus it is a daily driver...if I screw up I am screwed. I never see an ad in all the magazines offering complete rearends built for sale...just all the individual components. Anyone have a clue? Thanks A LOT.....Ken
