98 vortec flexplate to th 350 transmission

[keith nohner]

I just installed a 98 vortec 350 out of a wrecked 2500 chevrolet. I switched it to carb with a weiand stealth intake, everything was going good till I realized that the flex plate holes dont line up with the converter. The vortec motor had six bolts, the th 350 has three. I realized this, but I just figured three of them would line up. Which newer one piece rear main seal flex plate will I want to get. Sucks I already tightened the bell housing bolts, but At least I wasnt any further.
