CA WTB: Need factory door hinge bolts ('55-59)

[chevyrestoguy]

I am hanging the doors on my '55 and I can't find all of the original bolts. I like the look of the factory flanged bolts, but I can't find anybody that makes them in 3/8- 24. Most all flanged bolts I have found are coarse thread, and that won't work.

So- If anybody has them and aren't using them, I need 6 original bolts. Must be the flanged style with the serrated back side.
