Since their related and they may help you or someone in the future here are a couple of extras
The trapdoor hardware Jeff posted in reply #6 match the ones from my San Jose fastback - Oct 9, 1964 scheduled build date, Oct 18, 1964 engine assembly stamp.
Believed to be original.
L to R (threaded part measured, i.e. under cap to end):
Trapdoor Hinge screws: 3/8" x 8-32 (P&O?, no head mark)
Trapdoor Latch screws: 1/2" x 8-32 (Silver Zinc?, SEMS head mark)
Trapdoor Prop bolts: 3/8" x 1/4-20 (Silver Zinc?, R in circle head mark)
I think the bigger feat was getting them to balance on my leg.
