Detroit TrueTrac for GM 10 BOLT Part# 913A481. I bought it for mySilverado but since mine is a Mexican truck it does not have the samerear end. Apparently it has some sort of Dana unit in it.

I got it for $400 shipped and will let it go for $360 shipped. It isbrand new and still in the original box never opened. The shop that wasgoing to install it told me about the rear end being different than theUS spec trucks.

I will open up the box and take a pic in the morning.
