This AC Idler was used in later-produced 67 289 Select-Aire Mustangs and was often installed as a Service Bulletin "fix" for AC Belt deflection/rattle while using the AC at engine idle.
2- bolts are listed in the assembly manuals as 370807-S2 & 377379-S2.

AMK sells the latter of the two for the "OTHER" listings noted above but AMK does not seem to have one of those 4 1/8" lock speacial locking 5/16" bolts.
Does anyone else know how to find such an animal new? My old one is pretty much destroyed and it seems most "EARLY" cars wouldn't typically use them.
Last resort would be to manufacture my own but not what I was hoping to do.
