Power Brake Booster

Need an expert’s opinion on which booster is correct for 59 SF. The canister type (oval shaped metal case) or bellows type (fluted rubber case). I’ve seen both types on 59s. TIA

Both boosters are correct. Last week I received the build sheets of my car,
and mine has the fluted rubber case (Kelsey Hays). But they also used the Bendix booster. I read some time ago that it depended on the plant where your car was build. So they both can be correct but you don’t know for sure until you see the build sheet of your SF.

Thanks Ron. Guess I’m covered since I have both styles. Have a NOS canister (Bendix) and a Kelsey Hays that needs rebilding. Who did you get the build sheet from?
Thanks, Chuck

I will ask the man who arranged the build sheet for me if I can give you his name. Or maybe he will reply himself, he is one of our members!
