hey guys sorry for most likely a repeat post, but i’m installing my rear disc on my new build and i can’t find the correct part number for the master cylinder off a ‘99 c3500 **with rear disc** advanced and auto zones sites do not state w/ rear disc or not. i just want to grab the correct one the first time. i’ll continue to search in the mean time!
i’m keeping my factory vacuum booster also
