Vacuum can for 48-53 GM-style distributors?

[Ross F-1]

My 3rd Accel adjustable vacuum advance can just failed, it's a miracle if the damn things last 2 years. I want to run around 8 - 10 deg vac advance per Richard in FL/Ol Ron's testing. Is there a GM factory can that will provide close to that?

I'm running the MSD Ready-to-Run which uses the GM points-style vacuum can (non-HEI).

Couldn't find anything in a search, appreciate any help!
