For both the bellows style and the oval canister style booster, I recommend Karp's Power Brake of Upland, CA. They have a site at www.resleeve.com. They make the rubber parts to rebuild them and can also anodize the end plate of the bellows booster to look like new. I've also use Power Brake Exchange in San Jose, CA and cannot recommend them. By the way, I've also found that there is no rhyme or reason as to which cars got bellows and which got canister boosters. I've got high end and low end cars with either. Go figure. The man at Karp's said the 300 guys like the bellows style, and after thinking about it, it occurred to me that the only reason they would is because the gold anodized end plate dresses up the engine room more than a black painted oval.
