Does anyone know if this will fit a 70 Buick GS 455 with a th400, factory flexplate? Not sure about the bolt circle size.

Jeff, I would think so, but to be sure, pm Meanbuicks on this BB. Greg works for TCI, he would know for sure.
Don't Chevy-type converters use a nut/bolt combo to fasten to the flexplate, instead of just a bolt like our Buicks generally use?? Just a thought....doesn't keep it from working....just a thought.
You are WAY better off going with one of these, http://v8buick.com/index.php?threads/tsp-9-5-street-strip-converters-lifetime-warrantee.147066/ Jim knows Buick engines. Tell him what you have and you'll get the right converter from the get go.
