Would the matching booster/master cylinder from a '98ish Blazer bolt on? I'm asking this in lieu of the dual piston caliper/rear disc swap.

The bolt on part doesn't concern me so much, I asked this question more after reading this thread:

It brings up valid points of switching from drum to disc in the rear, and it would be ideal (imo) to start out with the original master cylinder (at least). That would at least get into a very close ballpark of having the correct pressure balance, and maybe put a prop valve on the rears in case pressure issues did crop up.

I just checked with napa and the master bore size is 1" for the Blazer. One of the same sizes as what came on our cars. The stock master is a good place to start.
