Oil Pan Drain Plug Size? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an 82 GMC Sierra with a SBC 350. I don't think it's the original motor, but the dipstick is on the passenger side.

Does anyone know the size of the oil pan drain plug?

Thanks guys.

The threads are 1/2"-20.

Stock drain plugs require a 9/16" wrench to fit the hex head.
