I have a 1988 K5 Silverado Blazer and I'd like to install a differential rock guard, and the only information I can find about my differentials is on the build sheet : GU4 Axle 3.08 ratio But it doesn't name the maker of it and calls it GM corporate differential. All I have is the build sheet to work from.
This was just before we finished it. It has a blue pinstripe running a 1/4 " above the red and all the chrome is back on.
