I need to know the correct location of the drain plug on the 3820000 oil pan. I believe I have the correct one, but would like to verify. Thanks, TS

The drain plug on the original GM #3820000 oil pan is located on the rear surface of the pan at the center bottom. It is on a slightly "flattened" surface at the radius of the pan where the bottom curves up to the rear surface. The replacement pan issued in 1975, GM #360866, has the drain fitting identically positioned.In Appreciation of John Hinckley- Top
