Well, it WAS the flexplate!!! <img src="/forums/images/graemlins/smile.gif" alt="" />

I went ahead and just had them replace it with one from Toyo. They couldnt find one anywhere else. Toyo charged around $250 just for the plate, leaving my final bill at $502. I'm not sure if this was a good deal or not, but definately better than the $2500 or so I was thinking for a rebuild, etc. Thanks for the heads up. BTW, it was broken just like that guy's was who posted the pictures.
