Does anyone know what the small case 3G that will fit a Fox originally came on?
I had a list of em somewhere but for the life of me can't find it.
In a situation where a small case is the only option.

Didn't they come on the '94+ 3.8L Mustangs?

Saw that Slope, thanks.
According to that, both I have here are suppose to be small case but are large.
Was hoping someone knew for sure what the small case came on and if it came in a 130amp version vs the norm of 90 or 95

Found it.
Looks like it came on the 92-94 Aerostar 3.0 plus 96/97 F series with a 7.4/460

90 amp or 130 amp? Is that mounting ear threaded?

I looked it up small case is 5-1/8" diameter, large case is 5-5/8" diameter The small case one is 95 amp, large case 130amp. and it looks like they both have the threaded mounting ear.

Yes got one at 95 amp small case.
This one came threaded.
Thanks for your input.

looks like the small case can also be 130A I looked up a 91 Taurus and it *looks* the same as the one u listed Rick

EDIT: I stand corrected another look up shows it as large case but will continue searching as I am sure theres a 130A small case I found before

Ran into a list that shows several are suppose to be 130 amp small case, all are large though.
Aftermarket high amp versions are available though.

I digress I searched thoroughly and a small case alt is only 95 except aftermarket

Yeah i was looking too, i give up. Closest i found was a 110 amp from a Thunderbird Supercoupe, but i'm not sure if it has the same mounting dimensions or what size the case is.

I found one site that called that alt a mid size case with odd dimension mounting tabs, not sure though.

The alternator on my Crown Vic Police Interceptors are small case, they are 200 amp - produce 132 amps at idle! There should be lots of these in the wreckers.

That'll likely be for the Modular motors. ZR is working on a pushrod mill.
