Right now, I'm specifically looking for 1/2"-16TPI BSF x 1-1/4" long. Those are Damper mounting bolts for the Vanden Plas 4 Litre Princess Limousine that I'm working on. Moss motors has the 1/12-16TPI BSF x 1-3/4" long ones for the lower wishbone pivot shaft bolts to hold it to the frame. Some Bubba left 3 of the damper mounting bolts off of this one, and used those shorter bolts as replacements for the lower wishbone bolts. They barely engage 3 full turns, and the bolts got pretty corroded and pitted down there. I'm planning to replace all the lower bolts, so at least I can use the 3 "borrowed" bolts to fill in the empty holes for the dampers. But I'd prefer new hardware all around, if I can find it.
