I installed my front drive shaft for the first time since I have installed my dual transfer cases. There is only 1/8 inch of clearance between the CV joint and the bottom passenger side bolt boss on the Marlin adapter. Is this enough? Do I need to grind the boss down so that there is more clearance? Anyone run into this before? The other question I have is the location of the traction bar. If I mount it so that it sits directly on top of the diff and then mount it to the center of the crossmember, the clearance on the drive shaft is very small. If I use a 3" shackle at the front then the drive shaft clearance is about 2". Is that enough for drive shaft clearance when both rear springs are compressed? Will the traction bar still clear the gas tank when the left rear tire is compressed up and the right rear tire is hanging down? Any input is appreciated.
