You can adapt the vacuum advance to the old pro billet. I run that one in Dad's GTO and i added the vacuum advance to it 25 years ago. It has the provisions for it and since I like to source my own vacuum cans and modify them accordingly iit was a non issue. Of course now msd sells them with vacuum cans, go figure, lol
