Dave, M2503S is listed as Chrysler # 1752461 for 300C engine # 3NE57 2962 and earlier. I could use a spare. Please contact me privately if you wish to sell. Thanks. Best Regards to all, Thomas F.

Both are Carter rebuildable types. Numbers are MO-1053 and 2503-SA on one of them and the other has M-106 and M2414 SA on it. Any one have any idea what these may fit or know someone with books that may help. I tried the vendor cross reference lists in the rear of the parts books to no avail.
