All that matters is transmisson and flywheel bolt pattern for the convertor to bolt to. As long as it is splined right on the tranny side and the tabs welded to it will line up with the flywheel holes, you can use it.

You need to get a TH350 converter. They make flexplates for one piece seal motors with the TH350 converter bolt pattern.
