Pair of OEM drum brake master cylinder bolts. Bolts go through the firewall into the brake pedal hanger. 3/8-16 x 2 inch long, indented hex head bolt. These also have the lead points, and SEMS lock washer. These are Grade 5 bolts. Not available anywhere that we have found, AMK offers 'a bolt'. Pretty sure that these bolts were originally phosphate and oil finished. They will most likely show some amount of deformity on the hex portion, these are hard to remove after 50 plus years. Limited stock.
