Door hinge pins

[Accelo]

I believe stock pins are 11/16" or .343 in diameter.
It doesn't explain your .395" pins.
All the original hinges, I have repaired, had plastic bushing in them.
The all brass bushings suggests your hinges may have been modified.
Is the OD of the bushing correct for the hinge?

All the hinge pins I have purchased have been longer than stock.
I believe the extra long pin is so the same pin can be used in both the early and the later truck. I cut them down to the stock length just because I thing it looks better.
Functional they are the same.

Interesting the Classic web site listed their pin measurement as 4 1/8
I can get better measurements when I get home on Friday if not posted before then.
Cheers
