Body mount bolt question

[muletownlj]

Hey all

I attempted to install some Fishbone sliders today . My 05 as a 1.25” JKS body lift. The person that installed it used new 4” long grade 5 bolts, not flanged so need a washer. Why would they do that?? The standard bolts are 3.5” and they added 1.25 so I figured they go for 5”…

I backed out the passenger side bolts out and jacked it up. All fine. When I went to re-install the bolts it feels like they hardly catch a thread. Then they just spin.

.
My thought/hope is that the 4” bolts are too short with the washer, bushing, body lift and adding the slider width. I ordered 5” bolts that are grade 8. BTW rhe 4” bolts cross threaded and damaged, the last 1/2” or so of them.

I’m terrified the weld nuts are stripped although I have no clue how it happened. Everything went so smooth before that.

Thoughts? If they are stripped I’ll have to take to a fabricator because I can’t weld…

Hopefully the long bolts will catch the threads because if not some type of fabrication will be needed, whether it’s cut a small hole in the floor to access the top or to cut out the sections from the bottom to weld in new sections or even complete torque boxes depending on how many you need to repair.

Ouch. It’s just one so far.

One spot , depending on location you could drill a hole directly above the threaded hole and get a longer bolt and use washers and a nut on top. Just an idea if you don’t have a buddy with a welder lol
