I agree that AMK is the best source. Markings on the Inline Tube Anchor bolts are not correct. The problem is that the selection from AMK for Pontiacs is a little spotty.

I have used both the Palmetto solution and Black Parkerizing Concentrate. IMO, the Parkerizing Concentrate worked better. You can find it on EBAY. The Eastwood solution is just a black dye. It is not a chemical coating that offers protection. I'll have to look into the Gibbs Oil. SOunds interesting and parts after Parkerizing need liberally coated in oil. I actually soak mine in oil for 30 minutes or so.
