I just dropped off my truck yesterday at my mechanic's, he's an older guy that has his shop in his garage, and is the best and most reasonable guy. He was going to put in my new 4.10's and Eaton Posi, but he called me today and told me he can't do it now cause someone stole his briefcase with all his guages and tools he needs to do the swap right! It was worth 2500$! And what really sucks is that now I have to take it to a differential specialist who wants to charge me 800$ instead of the 450$ I was going to spend before! I'm pissed, I hate thiefs!
