So i am doing a solid axle conversion over to a moser 9". i guess there is an issue with the stock driveshaft being compatible with the 9". So I am looking at getting a new driveshaft as well. I have the t-56 still but am trying to figure out what the drive shaft measurement would be for this combo. The easy answer is just to mount the axle and check it, but the rear end has not come in yet. trying to get the shaft ordered since i am in a time crunch. If any of you guys have any expierience wih this please post up. thanks alot.
