best vacuum booster/mastercylinder for vacuum brakes?

[JDSfastGN]

I am going to convert to vacuum this weekend. I need to go to the autoparts and order a booster and m/c. Is there a better year/setup to go with than just an 87 regal? Just wanted to see what you guys had to say. thanks.

BOP G-body are all the same ... dual diaphram. Some Montes run a single for some reason.
