are there any resources floating around about the various diameters and types of boosters which fit a third gen? I've seen that GM has various diameters of the dual (tandem?) diaphragm boosters, but have not been able to locate a reference such as sizes, model numbers, amount of boost provided, etc...

i did see a post a few days ago where someone posted a pic of a higher assist than stock booster, but I can't find it anymore. I think it was chromed (don't care in the least about the chrome though) if that helps jog anyones memory.

anyone have experience swapping in a slightly higher assisting booster?
