Re: brakes?

What's the year and gvwr of your 3/4-ton?

If you have one of the 1980's c20 or k20 trucks with the 7200-gvwr, then you should be able to easily upgrade brakes to the 8600-gvwr version.

The 8600-gvwr 3/4-ton trucks have a "c6p" RPO code on the SPID sticker, and they come with JB7 brakes. The 7200-gvwr 3/4-ton trucks don't have that "c6p" code, and they come with JB6 brakes.
