ISO: looking for a known working brake booster for a 73-76 A-body for disc brakes.

I don't think this vacuum reservoir for power brakes is worth messing with because I let the thing sit and penetrating oil and I still can't get m/c off of the vacuum canister...I just hate for you to invest in another dud

Thanks for checking for me. I’ve got a brand new aftermarket booster, I think I’m going to go with.
