If it's like the TBI cars, there are 2 different ones, one is stamped "negative" and the other is stamped "positive" - you'll have to match what was on your car - not sure it was a year by year thing, as I've seen 1990 TBI cars with either one.

Actually...just called the dealership....the part number for a 350, AT, TPI is #17113461. Can pick up AC Delco Piece at Rockauto for half what the dealership wants.
