LMGTFY

 

Thank you! I ordered it on e-bay and it is supposed to arrive Friday. Is there any chance anyone know the exact size so I can get a bolt so I can drive it down to Discount Tires to have them install my new wheels and tires while I wait for my plug? I checked google and nothing came up. I mean diameter and thread count.

 

I don't know the thread size but the GM Part Number is 24500661. They probably have one, the same SC oil plug was used in M62, M90 and M112s. GM had SC V6s in Buick, Pontiac and Chevrolet over quite a few years. Very likely they'll have one in stock.

 

There's a good chance it's SAE threads since the hex size was SAE as well. I'll try and find my tools to measure the plug in my spare s/c later today

 

The GM parts Dept had one. Thanks!
