Body mount bolts

I'm trying to install an addl body lift and am running into issues with the damn body mount bolts. I've read in other posts that they strip and apparently I need to drill holes in the cab to fix it but seriously 6/10 broken?? I was able to remove four and the remainder just spin and spin. That seems excessive for a 2007 for the bolts/ or nuts to strip or seize for what seems like a very important nut to keep the body mounted! Any advice or am I drilling?

I added the teraflex exhaust spacer on my 2012 jk and snapped 3/4 exhaust flange bolts. These things rust up quick. Had to take it to a shop to get it fixed. What are you going to do after you drill them out? Tap the hole? Maybe you have more skill when it comes to that but I wouldn't be comfortable with drilling and tapping the body mount holes. I'd probably do something wrong and the body will fall off the frame :P I've tapped smaller not so critical holes before and did an okay job.

I hear that they aren't actually stripped. The thread is already out of the hole and they spin in the mount. You should be able to pull them out.

X4 not stripped... I had to put A LOT of downward force on one to get it to come out... 2 others a fair amount of force... And 3 others... Nothing extra at all... Just came right out.

I've helped install a body lift on 3 JK's. The bolt uses a lock washer. It's hard to see because it's tucked up inside. The bolts are getting hung up on the washer.
These are what they look like.

Just grab them with vice grips and hit them out.

Jeep uses a capture device to keep the bolts in the whole while on the assembly line. Typically the bolt will be free of the nut in the body but hung up on the capture rings. Try either giving them a good yank or pull down on them while using an impact to "loosen" them and the bolt should come out.

Thanks I appreciate the help I was able to get them out with extra downward pressure but now of course a new problem. The bolts that came with the lift kit are a bigger diameter than the factory ones so they do not fit into the captured nut. Because of the 2" spacers I cannot find replacement bolts that are as long as the ones that came with the kit. The mfg says they are supposed to be the correct ones in the box but the diameter is much larger. I've checked with Home Depot, Pep Boys, and Ace and they have the 1/2-13 bolt but not the required length for the spacers. Any more advice on where I can find bolts that will fit? Thanks!

No one has ever heard of this issue? The diameter of the new bolts will not fit into the factory nuts and a bolt in length of the replacement in the factory diameter I cannot find absolutely anywhere. I cannot continue without these now so any more advice would be greatly appreciated!

Hold on.....you're putting a 2" body lift on your JK?

Why?

Try McMaster-Carr or Grainger for the bolts.

I had to pry them down with two large screwdrivers on either side of the bolt on top of the washer, they popped right off.

You need to find the thread pitch and then call these people. It's metric I believe.

COLUMBUS FASTENERS CORP. Home - Over 40 Years of Service to Construction and Industry.

Columbus Fasteners will get you almost any bolt in any length. Get the correct grade (hardness)

Also, check McMaster Carr.

I installed my ACE rails over the rubicon rocker panels. They needed some space 1/4" as not to rattle, so I bought longer bolts.

Here's are pics of the captured nut, and an access hole (from a 4 door JKUR) This one didn't want just didn't want to thread. I chased the threads and it threaded easily.
