If you know the length and diameter, you could probably get a box of hardened steel dowels for $5-10, as opposed to just one. I have a short one that came with my Crane cam, but its in a pile of parts in the garage and I'm upstairs in front of my comp. I'll see if I can find it tomorow and get you some dimensions.
Your In Luck!... I'm a Partsman At A Ford Dealership so I looked it up for you. The Ford Part Number You Need is... 384940 S (Ford Hardware Number) There is Stock In the Ford U.S. Warehouse's so any dealership should be able to order it in for you and have it in with in a day (Or longer depending on were you are located.)
i tried with the ford dealer by me, and he said he could order it, but woul dhave to be in package of 5, since its old. 11.52 for each, so i wasn't about to pay 55 for one pin
if anyone has anymore for sale ill send money, i need one bad!
