Mopar Performance electronic ignition vacuum advance

[superbeedave]

Hey Guy's,
Where can I find a new vacuum advance for my Mopar Performance electronic ignition distributor for a 69 383? Also when you buy a rebuilt point distributor for a 69 383 where do they get the vacuum advances they put on them. I would like a new advance for my old point dist. I bought 2 NOS advances in the last 7 years and just sitting in the boxes and not being used the diaphragm goes bad and the then it doesn't hold vacuum.
Thanks, Dave

Rockauto... everywhere. Nothing special, is the same than the stock one

I bought mine at Summit Racing. If you recurved your distributor, here is a list of vacuum cans and you can pick one with how much advance you need

The advance can be adjusted... they can get a diff lbs rate though

I get mine at Napa, they still have the old books with pictures of the advance cans along with part numbers ...
