Ok - here goes. Since I'm "re-vamping" my car a lot - with lots of new stuff, I was considering upgrading the rearend of my car - I'm kind of afraid that with all the new stuff (exhaust, headers, polyurethane bushings, mounts, and suspension), that I'm gonna blow my 13 year old 2.73 rear end. As most of you can relate, I'm not easy on my car at red lights

Sooo - my question was this - has anyone done a rear end upgrade on their 305 TBI with a 2.73 rear end? If so - what did you upgrade to and how much did it cost?

I swapped mine from a 3.08 to whats in my sig. Bought the posi on sale. Total cost for all parts was about $600. Labor was $250
