Man this rear end is making me feel really stupid! I fidled with the left axle in the right side agian and finally got it to slid in perfectly, I wasn't lining things in right and didn't want to force it and break anything. Dam I feel stupid! so I guess I'm looking for a axle 37.5 inches long the flange is 4.75inches wide with 8 bolt holes that are 5/8th inch wide and the bolts are 1/2 inch with 16 teeth.
I belive the transfer case mysterybox does have a high and low setting for axle speed.
