F engine alternators mounted low on the left side have different "clocking" of the pivot bosses vs. adjusting bosses than the 2F alternator mounted on the upper right side.
F engine has bottom at 6:00 and top at 1:30 looking towards fan. 2F has bosses at 6:00 and 12:00.
The 2F alternator's adjusting boss drops below the stock straight-slotted bar before the belt is tensioned. The F alternator positions the adjusting boss further down the side of the alternator, so the straight bar works fine.
Some have used a curved bar for mounting the 2F alternator on the lower left side.

Alternator Questions
1978 FJ40 2F Production date: Nov 77 The OEM part for my year FJ is discontinued and the specs list it as a 12 volt 40 amp. The replacements I am finding are 65 amps. Does anyone know where I can find a 12 volt 40 amp alternator for my production year? I know I need to replace my voltage...

thank you very much for posting this @73FJ40
Old thread revival. But I have a question about the drive belts above. I have the 99323-01040 on my 69 fj40. It was a tight fit. I just replaced the alt and adjuster with one of Matt's nice setups and the belt no longer fits with new unit (same clocking and location but 55amp instead of 40amp toyota). Seems like the Toyota v belt 99523-11067 would be the solution, but it's unavailable. Anyone installed a new belt recently and have a part number? Aftermarket or toyota.
