Looking for a power booster for a 70 power drum car. I am hearing that I need a booster with the infamous upside down Delco stamp. Does this exist in any form in today’s market?
Call Booster Steve @ 503-248-8882 Power Brake Booster Exchange Tell him Eric sent you He should have the answer!
Here's the one one I have. Will need some TLC on the surface and replating. I have the whole assembly and may have one more, too. The cover is the worst part Can check tomorrow morning for the other if interested.
If you have a correct but pitted example, they can polish or grind them smooth and touch up the Delco stamp with an engraver. Not cheap or quick but if you are doing a concours resto it’s sometimes required in order to save a correctly dated booster. Depending on how picky you want to be there are different fonts used on the Delco stamping too. Skinny O and round O.
I’ve seen both. I pulled these out tonight. Both off of 1970’s even though the one has incorrect 71/2 master cyl. When the replated one was done looks as if they buffed the lettering almost completely off. The one I used on the silver mist car was from “the right stuff”. Pretty sure it was upside down
It was indicated to me that it would be points off for the "right side up" booster at MCACN. Also need bleeders on my master for power drums.
I have a master with bleeders, but it came off a disc/drum car? It would need to be rebuilt... Let me know if it works for you and I could get it moving early next week. It came out of a 1969 Old 442.
I seen a reproduction one for sale on Ebay before with the upside down markings. I thought it was a mistake so I passed on it.
That's a different master than what I need...mine is smaller and not the "fat" style you see on most cars.
