I'll dig around in the building this weekend & locate it & get the numbers. I still have it, moved shops about 16 years ago & I know I saw it then.

On the booster for my car, it's the original & has been off the firewall once, 2 years ago. I know this car since new & my memory is far from perfect but I'll guarantee I'd remember pulling that booster off before that. It was kind of a pain. I had a slow bleed off & tried to buy a kit from Dewey's but they wouldn't sell it due to liability, or that's what they said. Anyway, the finish on it was still very good (except small streak under MC, where it leaked on it, in 1980) so I didn't have them re-finish it when they repaired it. FWIW, the disc cars I've seen are painted black but, it's a different style booster, too.
