who makes rebuild kits for A body power boosters

Hey Don,

What does booster dewey get to redo one with all new cad plating and all?

Does he do these on exchange? Reason being is i have a 67 booster for 4 wheel drum, and a 74 disc drum booster. I plan on using the 74 as my whole brake system on my 67 is either 74 A or 79 B cordoba.

Maybe he would be interested in an exchange, and 1 extra booster as another core, maybe to get the cost down on an exchange.
