Sounds like you do have 4.88s. Want to trade for some used but good 4.30s I have laying around? I can deal with the buggered used gears... I'll ship mine and you ship yours.
In all honesty the most cost effective route for you would be to find a good used 4.88 third from a '94 or '95 4Runner automatic. I know a guy who probably has one. Wolff Auto... (406) 273-7213
