LS flexplate but you need to use a spacer like shown above....if you have a flat LS flexplate you need a different spacer that bolts to the crank then you bolt the fp to it but if you have the dished LS fp you can use the one above from hughes, it goes between the the fp and the tc

Same one I went with. And I had a converter from Lenny at Ultimate Converter Concepts which was built for a LS1 engine and th400 trans so I didn't need any spacer or anything.

You will have to use the GM spacer with the flexplate. And yes it should work with any LS bolting to a TH trans. Watch out for the early motors with the extended crank. And its SFI approved. IIRC it cost me around $140. Eric L
