C1 gas tank door screws

[Larry P.]

Can somebody tell me what size screws are used to attach the gas door on a 1960?
I assume it was a self threading screw with a hex head.

Larry,
Those screws are a phillips head screw, thread cutting , screw with a very large, external tooth lock washer which is captured under the head if memory serves me right. This washer is the key, since you will notice, that the hole in the door is large enough to allow the screw head to pass through. I don't know if anyone reproduces this screw or not.

Thanks John. This is what happens when somebody doesn't mark and bag when they take it apart.
