Guys,
May I appeal to your knowledge about a brake booster fitment question. I have a '64 Riviera and a '63 Invicta, and the booster on my '63 Invicta is failing. I thought the booster would be identical to my Riviera, but the vacuum lines on the '63 attach to the top of the can in a Y sort of fitting; on the Riviera, the lines are on the front of the can. Are these booster interchangeable? Most sources I have found list 1961-2 and 1964-6, but leave out the '62 models. I am also guessing, perhaps incorrectly, that the Rivera booster is the same as other full-size Buicks for '63-'64.
Is it possible that an early '63 car would have a '62 style booster? I am just confused and want to make sure my '63 has the right booster. Thanks! Rex
