Alternator Bolt - Missing, Gone,,, Not there.. 1992 Mazda Miata

I pulled into the garage thinking I would tighten up the V-Belt on my alternator because it was squealing. To my surprise the bolt is gone.

So,,, how do I find out the correct size bolt to replace my lost one and who would have one within the DFW area?

I have a 1992 Mazda Miata, standard with A/C and power steering. No Turbo.

Thanks for your time,

People on the pointy board are saying 10mm 1.25 pitch 20mm long.

Here is a link for that bolt from Rosenthal.

Here is a kit with two bolts and adjustment block.

I don't see the links... thanks though

Works for me ya gotta click on the Word "link" and "Here" in the above post.

Another try, link.

I think that bolt is 10mm, 1.25 pitch, 105 mm long.

You might check with Rogue...he has a huge hardware collection.

If I remember correctly, you might need a locking nut on the other end or it will come out again. Poor design if you ask me.

Local mazda dealer.

Started early this morning on my quest to replace the missing bolt. Thanks to all for clues on what I was looking for and where possibly to find it.
I searched at the following but without any luck... Duncanville Napa, Arlington Napa, Arlington Nuts & Bolts and the Mazda dealership in Arlington. Nothing zippo.
However, my luck changed and Rosenthal Arlington Mazda was able to provide a part number 9980-01-0105 and you where able to provide dimensions (10mm, 1.25 pitch, 105 mm long) and then off to the races.
I contacted Mazda Heaven in Ft Worth and Angus & Mario said that all those types of bolts are just placed in the trunk but perhaps one could be found. Sure enough Mario was able to produce one.... THANKS MAZDA HEAVEN!!
So overall it took around 6 hrs to find the missing bolt and 1 hr to replace. Alot of effort to get this thing running in time for my son pick up around 1:30 today. He requested to use the little car while he visits from out of state. Turns out now he found other transportation so my rush to make repairs was in vain.

I do have one more question. I have heard directions on how to install the bolt. Some say install from the "back". That is the bolt head is on the same side as the firewall and the nut on the side of the radiator. Or,, just the opposite.
So.... whats the correct answer?

Thanks for your help again,

Yes, from the back.
