gotcha, I was planning on moving the trans toward the back of the truck and extending the output shaft so it will stick out the front of the trans and use that to drive the front end. I have no parts gathered yet so I havent checked fitment of this. I was just looking at ride heights the other day and realized with a driven front axle it would be difficult to match the ride height of the solid stock axle.

With the Mack cab I have it lowered as much as possible, I actually cut the cab in the front to sit lower on the frame to get it to look right. So Im not sure if its worth it to jack up the whole truck to gain 6x6.
