Really, I will have to check that out. The rail would have to have the supprts under the cab, because there is only about 12 inches of frame available to mount a foot to behind the cab. How many angles are on that part of the frame? Mike says he has a Comanche at the shop, he will be able to work off of that. I just don't know if it is a LWB or SWB? offroader461 - heck yeah, give him a call. I believe the timing is right, a few MJers have expressed interest, and he has a Comanche at the shop giving him ideas!
