I know I'm going to get the stupid question of the day award with this, but...... In a 4x4 do you have to run the same gears in the rear as the front? Can you put 3:90 in the rear and have 4:10 in the front? I have a shot at some 3:90s and a locker diff for a good price.

I have a 72 f250 4x4 Highboy, 360 2bl, 4 speed, Dana 60 rear, 4:10 gears. I get about 7 miles per gallon. Is that what I should expect?

I have a f250 highboy. The data plate on the drivers door says it was built in Sept 72 at the San Jose plant. The VIN says the truck is a 72, but it has a 73 body. The truck has been painted so I can't tell if the paint code matches. The interior code does match the red and black interior. All...
