Haven't tried it myself, but someone said a while back that one of the big bolts that hold the front tow hooks on, or bumper bolts will fit. Please post if it works!

This worked great it's also the same bolt as a fj60 tow hook. Both are a little long but a couple lock washers fixed that and I think it will hold till I get back to civilization!

The thread listed above is correct (12mm X 1.25) and 40 mm long. A 35 mm would work in a pinch if that's all the store has (from experience.)

Ahhhhh! THANK YOU! Perfect. Ordered.

Might have to order up a set for both sides when I do my brakes. Keep the old ones as spares!
What about the rear caliper bolts?

The rears tend not to be an issue. The fronts seem to like to walk away.
Crazy, my bottom one just came out yesterday, glad to know it's relatively common and that I'm not alone in this! I just ordered from Amazon before I saw this thread. There are plenty of links, but just for posterity it is a M12-1.25 thread at 40mm long!
Also with these being metric, make sure you get a class 10.9 or better. I just had a guy try to sell me a class 8.8 and he honestly thought that it was equivalent to a grade 8 SAE. Class 8.8 metric is equivalent to a grade 5. So it looks like I'll be surfing Amazon in a moment. I do generally try to frequent local businesses, but that seems to be working for me less and less frequently.
Oh well...

If it won't torque to 90 F.P. it may not be bad threads, but in fact is the wrong grade* bolt. A lesser grade bolt will not be strong enough to reach 90 foot pounds of torque, but will stretch under that much torque. *Note, calipers bolts are in fact a SAFETY item, and should NEVER be replaced with ANYTHING other then the exact same grade bolt. The factory caliper bolts have the number 11 imprinted on top of their head, denoting their high strength.
Yes he just bought new correct bolts and lost one so yes the threads could be boogered

Get spares while you are ordering.
These are on the list of stuff that gets torque checked periodically and before every trip. Also have two new bolts in my small stash of parts I travel with. Seen way too many people post "one of mine is missing too!"

Just got back from a trail. Lost the front driver had to remove one from the transmission to engine to get home. I little longer just added some washers
FYI if you are in the middle of the desert and your caliper falls off and the loctite you put on it won’t keep it on because the threads are so boogered and loose for some reason.
Hopefully the little border town will by some miracle, carry a tap for a 1/2” 20tpi and a couple bolts, and you have to remove just a little sliver of material for your desert field repair. And then you red loctite the crap out of those bolts ...
You know theoretically if that were to happen.
