Alternator upgrades ford only, no GM krap.
How about a 1G 100A alternator off a 87-88-89 taurus. Its a bolt on to EB without factory air, or smog pump. You change the pulley of course, unless you are running serpantine. But it uses the stock external regulator for those of you who like to keep the wiring stock. If you want this alt in 200A, pull one off a 88 ford diesel with dual batts.
If you want internally regulated, pull a 3G that fits well on the EB, off of a 94 T-Bird with 3.8 or 94-95 mustang with 5.0. Good for 130A.
