1976 thru ??? pump for many GM lines. Date is the 103rd day of, probably 81 or 91. The last two digits are not anything I'm familiar with. Circa 69, the last two would have been shift and pump model.

Thank you.

Probably 1981, as I acquired it around 1988-89. I currently have installed on my 1972 Chevelle and was wondering how close it was to being correct.

Appreciate the help!

What date was your car built? I have a pump dated for a '72.

I also have a `72 dated pump here if needed.
