Mark, check into the 3.0(gas) flywheel being the same. I've got a flywheel on one of my engines, I can have mikerob run out and measure the diameter, and count the teeth. I knwo the 3vze(gas) has the same 8 bolts to mount it, and from the diagram, and the picture, it sure looks the same, so that seems like the best bet to me. 
Sorry, I can't find any of my books that have my parts lists in them 
although I did find this link that may be helpful (it contains a download for the toyota database of part #s supposedly, I don't have time to unzip it, and burn it to CD right now) the link is the Toyota EPC#1, EPC#2, and EPC FAQ near the bottom of the page.

Black dog,
Get some pics of your flywheel and measurements.
I need to know the overall diameter of the flywheel where the ring gear is pressed on.
Tooth count would be nice, but I am sure the tooth pitch is differant.
Also how thick is it? what is the bolt spread on the crank mounting center to center across the middle? what does the center hole measure?
Is there a shoulder on the crack where it mounts of on the V6?
