On a recent post I was trying to pin down the type of MC used in a 77 B. It seems that the square reservoir was used. The wedge was used on cars from about 75 to 76. Apparently my DPO switched out the one on my B at some point in time. The next big issue has been trying to run down the proper rebuild kit. There is a major difference in the vacuum seal used between the two types of MC. There might be some difference in some of the seals. I found the proper rebuild kit for the wedge master on a site called https://www.moonlightmechanic.com (I have no finanicial interest in this site) I will compare the parts in this kit to the parts for a square MC and post the differences. Stay tuned for further developments.
