Pulled the T10 out of my chevelle a few weeks ago and always wondered what kind of car it came from. While wiping the top down noticed these numbers 834P153499 on the front edge of the top of the iron case. Did some looking and could possibly be from a 63 or 4 Pontiac Catalina???. There is a casting date on the iron case of M23, 5.23.63 on the tailshaft and 3.63 on the cover. Could this be a pontiac vin or some other identifying numbers. Thanks. Mark.
