I did a quick search for brake boosters being used with a 1" bore MC (aftermarket) and didn't really find any thing. Will the stock booster from a 78 accommodate this? What aftermarket boosters are available to support this application? I was looking at the booster below, but there is not a lot of information. The bolt pattern 3 3/8 square, but I'm a little concerned about linkage.
