I got my Flexplate from TCI and they married it up to my converter just to make sure it was correct. You will need a TH 350 or TH 400 converter.

You can get the TCI LS1 flexplate and have the converter made with an LS1 hub. Having this done now. I am putting a TH350 in my Z.

Make sure its made with 1 piece LS1 pilot, not a welded bush to extend the pilot as this is whats giving me grief, was wrongly informed about a converter purchased what I was lead to believe, when it arrived it was a welded on bush extension and now my run out is 0.025" on the converter, it doesnt run true, so now I need to send it back.

btw it was NOT from a forum sponsor.
