70 brake booster
 

Deseperately need 1 or 2 very mint restorable 9391 brake booster cores. Prefer early 70 dates but will work with what I can find. No glass or sand blasting done to them, no pitting, no scratched just virgin boosters. Prefer the Delco Moraine stamp on the bottom left of the front plate as per the attached. Email or PM me with what you might have.
