1982.
If Honda Motorsports was in charge of rebuilt Chevrolet V8s, I bet they'd charge $100,000 for each one.
I have the front calipers apart right now. The pistons are serviceable (not perfect but not shot) and the bores are as well. I'm going to re-use the seals, as the piston seals aren't torn or overly damaged. The piston dust seals look kinda crappy but they aren't torn either so back in they go. The slider seals are bad but I'll put em back on anyway and just grease the slider pins generously. The main problems I'm dealing with at this time are corrosion in the seal grooves, and one piston (ain't there ALWAYS one???) that won't come out with air pressure.
For cleaning out the grooves I guess holding an allen wrench with a pliars makes a sort of OK cleaning tool. For that last piston I'll have to complete servicing the other front caliper, install it, reconnect the other caliper to the line, and pump that SOB out with hydraulic pressure.
