They don't rust that way. :D
Should probably talk about them, but I'm too tired to start that over there..
Chrysler spec'd the torque on their 7/16-20 wheel nuts at 55 ft-lbs.
AMC spec't the torque on their 7/16-20 wheel nuts at 75 ft-lbs.
Can't recall what GM spec'd their, think it was also around 70 - 75.
