I have a 1994 GMC K1500 Z71. It is my understanding that all Z71 trucks have a locking diff in the rear end. The RPO code sticker in the glove box confirms the Z71 package, but there is no G80 code. Only the axle ratio code. In testing, I found the rear end acted like an open diff. I fully expected to find an exploded Gov bomb inside the housing. This morning, I pulled the rear cover to find an open diff. This is OK as I'm going to install a lunchbox locker. Am I misinformed as to the standard equipment on the Z71?
Thanks for any help you may be able to give.
