Default Alternator Question

Hey guys, I am new to this section. I recently acquired a 1990 f150 and she needs a little TLC. I'm trying to figure out what alternator I need. Its a reg cab, long bed, inline 6, 4 speed manual, XLT Lariat, power windows and locks, A/C. There is various options 60 amp, 75 amp w/ or w/o A/C or optional elec equipment (I'm not sure what the optional equipment is), and 80 amp. I'm hoping some of you guys can shed some light on what I need.

If you can get a number off the alternator if it is still a ford one in there i might be able to cross it to the service part number

You might want to consider a 3G alternator upgrade. It's very easy to do it.

Definitely the later 3G, and there's no reason NOT to get the 130A version. Click this, read the caption, and continue to the NEXT several:

There are more relevant links in those captions, so keep reading. But ultimately: it's barely any extra work to swap in the VASTLY-better (and safer) later-design alternator.

Thanks guys. It already has a remanned alternator so no chasing part numbers, Iíll look into the 3G alternator.

Have you done the swap? If so what was your donor vehicle?
