member... where you'd use a shop jack to lift it... I've used the tension rod mounts myself. But the frame rails are the best place to put them... And its where you're supposed to put them according to the service manuals. Anyone else cringe when the bastards at the dealerships try and lift it by the fenders??? grr... I about bit one guys head off for trying to do that. Frame rails are only another 6" inward... use your brain man!!! Sheesh!!
