Rear Shackle Bolt size?

So the bolts to the rear shackles were seized and long story short I am going to need to tap new threads.

The old bolts that came out seem a bit warn and boogered and I am going to try to re-tap the threads on the holes.

Can anyone confirm the size of these rear holes? 86 CJ7

I've read that they are 9/16th not sure on the pitch size... I've also read in other forums 7/16 and M12

Thanks in advance for the help!

Can't say for sure about a Jeep that new, but my '78 uses 7/16-14 x 1 1/2. Since you have a wide track they might be different. I would very much doubt that they used a metric on a CJ7, but I guess it's possible. I don't think my CJ had a single metric thread on it.

LOL very funny.... Thanks for the info there. I haven't found a metric on this 86 either.

Actually... I wasn't sure what to call the bolt I was referencing and I think I gave you the wrong bolt info.

Im talking about the shackle hangar bolts. The 2 bolts that hold the shackle to the frame.

Those are some of the few bolts that I've never removed. I removed the front shackle hangers around 20 years ago to install a shackle reversal kit.

I think Jim is correct as for the shackle bolts.

The 80 CJs' have metric power steering pumps and the T4 and T5 transmissions are completely metric.

My notes from the restoration just say "Rear shackle 7/16" and "Rear shackle 7/16 x 1 1/2" so I suspect that the hanger bolts are also 7/16".

On my CJ the welded-in nuts were rusted away, so I cut about a 1 1/2" hole in the rear crossmember to give access to the frame tube and slid flange nuts inside. I wanted to cut that hole anyway for access to flush mud out of the frame. You might consider doing that too, because mud in the frame is a significant contributor to rust. Take a look at my website, BDashFab.com for more ideas on restoring an old, rusty CJ.
