Don,
I was cross referencing your Napa number 36367 with A1 Cardone and Bendix numbers at Checker. That Napa number comes back as a master cylinder for manual brakes. They listed some different part numbers for 1976 Corvette master cylinders for power brakes that cross reference back to a Napa #39018. The Napa website has the 36367 listed for manual and the 39018 for power too. I was doing it on the computer so I can't see what any differences are. Just wondering if there were reasons why you use the manual Corvette master with the MII booster instead of the power Corvette master.
Also, Checker has the remanufactured A1 Cardone and Bendix Corvette master cylinders for $15 to $30 with $5 to $10 core charges. You can find them at
www.partsamerica.com. A lot cheaper than the Napa one For $90, but maybe comparatively the're junk. Anybody used any of the remanufactured ones with good luck??
