Looking for some fasteners

["Vito Pacione" <vito@argohouston.com>]

List:

I am trying to locate a source for the bolts that were used to mount the
body to the frame on a TR-6. These are 5/16 X 1-3/8 bolts with a rounded
head (called either a leader point or dog point, I think). Overall bolt
length from tip to tip is about 1-5/8"

Does anyone know where to buy these?

Better yet, does anyone have any really nice ones that could be blasted and
re-plated? Mine are just too far gone.

Thanks!
