I'm restoring my 87 2dr 2wd blazer for a daily driver, auto with 3.4 engine,dynomax cat back. I just installed the 2000 7.6 disc brake rear and with a little research found out the 2000 front disc can be swapped. Just wondered if anyone use the master cyl and vacuum booster from a second gen. I also have a first gen with a sbc that's getting a disc brake 8.5 rear and the LS1 front brakes ...but that's another project.
