I plan on putting 2 TCS solenoids up on EBAY to see if anyone wants/needs them for their restorations.
Both were pulled from 72 455 motors. However, they have 2 different stampings on them. One is stamped
10 H 71 and the other is stamped 11-H-71

What is the difference? I don't want to misrepresent them and want the right part to go the right car. Is there a "numbers matching" application here like there is with carburetor numbers?
