Can you tell me what the torque specification for the nut holding this main gear?

Willys Jeep Parts Tech:
Depends on style nut you have. Please email mike@kaiserwillys.com and I can help out. Thanks!

Is this tank lined or galvanized to prevent rust?

Willys Jeep Parts Tech:
No, but it is not required. As long as you keep non-ethanol fuel in it, they cannot rust out when full.

I'm a little confused by the images here. I've got a gear marked 18-8-19 and has the raised chevrons like the second picture. Does it matter which one of the two I receive?

Willys Jeep Parts Tech:
We get these from different suppliers and we are showing both sides of the gear.
