Those tufskinz ends are not what you need. Im pretty sure I have what you need in the garage, swapped to a metal rear bumper on my wife's bronco. Had to swap the sasquatch end caps for regular bronco end caps. I'll dig them out shortly and post what I've got.
At 300 bucks it's hard for me to pass this one up.
I'm up in Oklahoma camping this week, I'll be back Sunday. If you still have it next weekend I'll meet up with you.
I'm north of Mckinney. I'll be swapping out tires to 37s in the next couple of weeks if your interested in the factory 315 70r17s. About 8,000 miles on them now, won't change much as its not my daily.
