Yeah I plan to drill and tap all the way through each side, get a blt long enough to go all the way through, and add a lock nut on the inside. I wasn't paying $70 bucks for (imo) ugly Trex sliders. I paid $10 shipped for some black ones on amazon.
I've got the rear end sitting in the shop... being reevaluated lol! I hit a snag and I'm not sure how to proceed without modifying the frame in some way. I saw this coming, didn't want to accept it until it was too late haha! I'm still working on it though
