Okay so there are about a million of these 3g swap threads, so I think I've got the details of the install covered. But, what all the threads seem to not address in much detail is what to get if you're someone who is ordering a new/reman 3g alt.
I know that for a 3g swap into an idi the alt from the 90s and early 00s 3.8L V6s fit, but other than that the details aren't really specific, except that it needs to be the 2 ear (& 12 & 6 o'clock) 8.25" spaced pivot style 3g alt, which is info that online retailers don't really advertise.
So I guess my question is, what model #'s work in the v-belt idi's? I know the 7756-3n-2g is a go-to standard, is there any others, or variations of? I'd get the 77563 but I can't seem to get it here in Alaska, but I see others that are similar with the serpentine pulley that are $90 that will ship, but no info regarding whether they're the small cased alt or the large cased alt...
How can you tell the difference between the 7" spaced small case 3g alt and the required 8.25" spaced large case 3g alt? The world of alternators is very foreign and confusing to me...
