Mack M75SX

[Jared]

Looks good! I've been following along partly because I don't know much about Mack off-highway trucks and because it's so different.

I was curious how the tandem axles would be driven. Not trying to be nit-picky, but is this the way the axles will be oriented when they go in the truck? If I'm looking at them the way I think I am they may wind up with one spinning forward and the other backwards unless one is flipped upside down. The front axle ring gear will reverse the rotation of the jackshaft. You may already have that taken into account but I would hate to see it happen. Years ago, a couple guys from my area built a monster truck from surplus army truck parts and when they were ready to take it for a drive the axles turned opposite! I'm not sure if they ever got it driveable.
