Yep I am looking on there. I saw they have 5/8 as well. How do i figure out which one i have?

Easy. Whip them out and measure them.

Don't know about yours. Olds G-body uses the 5/8" as well as other Olds models. GM p/n 565006, superseded to 2973932. I suspect yours uses these as well, but I don't know for sure.

The 1/2" deals are 25015169 superseded to 25085970. You can tell just by looking at them. The 1/2" has no "notches" in the perimeter of the socket. Plus it's a bit narrower, obviously.

GM 1/2" ones are usually blue. PC168 is the ACDelco number.

That is what i was looking for. I bought (4) 1/2" from Rockauto, seems to fit. I didn't know how to properly measure them until i asked my father lol.
