Where can I find a ported vacuum switch for a 79 Buick regal engine 4.9L 301?
Wow, that's a tough one. If you were looking for the 5.0L 305 you coul get it through almost any online source. :(I recommend giving these guys a call:http://www.theautopartsshop.com/While they don't stock the part you're looking for, they have the switch for every other model of the Regal engine made that year and may be able to turn you on to a solution.Calling the dealer, a Kragen/Chief/etc auto parts store and/or your local auto junk yard(s) are also decent options. Good luck!
