Hi. I am going to need to replace the upper alternator bolt on my 3.8L 1995 mustang. As best I can tell from searches is that it is part #56543-S2 (discontinued) which has a 3/8" diameter and 16X1.75" shaft. The closest I can find at a place like Advance Auto Parts (online) is the Dorman - Help Alternator Bolt which has a length of 3-1/8". It seems that bolt would be too long and run out of thread before it could firmly mount the alternator. I have looked on the LMR and CjPony parts sites, and they appear to have nothing appropriate.

Can anyone offer suggestions where I could locate an appropriate alternator bolt closer in size or perhaps some other attachment approach? Thanks!

Try an home improvement store you can look thru the bins to find what you need.
Alternatively, try fastenal they have everything.

It's only an inch or two. What's the big deal?

You can literally look for weeks for a bolt like that and never find it. Go to the hardware store and buy a short stick of all thread. (Threaded rod) cut it to length, file or grind the end smooth, and install it with a nut. The whole front of my son's engine accessory drive is assembled like this. Quick and easy.

I want to measure mine. It doesn't look that tall.
