HELP... caliper fell off...

HELP... caliper fell off...
Okay well the title pretty much says it all, my caliper bolt went bye-bye (the top one) on the front left, and the caliper fell off halfway, ruined the inside of my wheel and tore up the caliper itself pretty good. Where can I get a new bolt!!!??? No one has the big black bolt that hold the caliper onto the bracket, I even brought the bottom one around to several places to compare and can't find any bolt like it. I can't seem to find a part number or anything either. Anyone have this info?

The bolt that holds the caliper to the bracket or the bolt that holds the bracket to the knuckle?
I have a drawer fukll of bolts that attach the caliper to the bracket. It threads into the guide pin. New ones come with rebuild kits. I would be happy to drop a couple in the mail to you. I'm not sure of the size or thread pitch.
If it's the bolt that attaches the bracket to the knuckle, that will be a little tougher to find the proper size and GRADE. It's a 10mm x 1.5 pitch (or 1.25, sorry, it's from memory). But it needs to be a grade 10.9, not the standard 8.8 you see typically offered at Lowes or Home Depot.
Or, you can drill out the threads in the knuckle and bracket and insert a pair of 7/16" (1/2" would be better) grade 8 bolts and use nuts to secure.
If it were mine, I'd drill it out and use bolts and nuts.
Use locktite blue.

Clearance between the rotor and knuckle is the most critical. So, you might need to put the bolt through the knuckle first and fasten it with a nut on the back side, having the bolt head against the rotor face. Might have a hard time finding the exact length bolt you need to have the threads hanging out.
Before you drill, make sure you can get a wrench on both bolts with the caliper in bracket in place.

If you have a GOOD parts guy at a dealership, he can probably find out.
If you have a Fastenal distributor close by, they could probably find you a match. But, most Fastenal places will only sell fastners in quantitiy, not singles.
I cannot stress enough to make sure you get the same GRADE bolt ...

I cant believe you walked into a parts place and they looked at you with rolling eyes.. I would ask if they have a thread gauge- to check what the threads are.. or just go in their nuts and bolts section (NOT HOME DEPOT/LOWES, they do not carry enough metric stuff) and start pulling nuts out of packages and checking the thread size and pitch. Not very difficult, I would never resort to drilling the knuckle/bracket, thats a hack IMO.
