just switched to vacuum brakes, problems!

[tyson]

I just switched over to a vacuum set up off a 85 regal. When I started the car after switching over I could hear a(hissing) vacuum sound coming from under the dash and the car is idling bad now. I assume that the a seal on back of the booster is leaking. Can I buy a replacement seal or do I have to get a whole booster?? Can't seem to find anything on autozone or oreilly's web sight for just the seal.
Thanks,Tyson

Remove the vacuum connestion to the booster and block it off. If the leaking sound stops it is the booster. R&R. If the leak still exists, check the vacuum connection on your cruise control switch.

Just get a hydroboost and be done with it! Vacuum (once leaks are stopped) will work fine everywhere but on starting line when you are trying to build boost.
