1980 Olds Cutlass Calais

[xlarshn]

So I find myself needing to replace the brake vacuum booster after 30+ years of faithful service. Autozone lists two potential boosters, a single diaphragm and a dual diaphragm booster. First, how do I know what I currently have installed, and second, will the dual diaphragm booster work in my car. I have an Olds 350 currently in the car. For reference, here is a link to the boosters in question

More then likely, and if the dual will work, I will end up purchasing the dual diaphragm unit with the master cylinder.

Thanks

Actually, you have a 3rd option you probably didn't even know about.
