Bill,

Many restamps use original over the counter units which were not stamped at the AC Delco plant and were shipped blank. They have the original AC Delco embossed logos and correct style cases but no numbers. I bought one of these recently and they are prime candidates for the guys who are restamping numbers whenever they can find them. The obvious fakes out there will often have the cases milled down to remove the original numbers and are then restamped. These are easily spotted when you look along the top edge of that surface area as you can see a milled ridge line along the surfaces just under the mounting boss and can tell its had the surface milled down. Original cases should be level across that area and it runs flat and true right underneath that front mounting boss. There should be no ridge or drop at the base of that boss, just a level field running right underneath it.
