Im running a 6.0 ls LQ4 with a powerglide,,Ive tried two different flex plates, neither will match with my components, this one I have now will not mess with the starter properly.

Does anyone know what will fit for sure,,its a bunch of work pullin this trany out !!! lol.

A part # would be great, Ive order 2 now from Summit, and they dont seem to have a clue....which one I really need.

 

I would get in contact with tci or circle d.

 

You may have the long crank 6.0. Which might explain your flexplate issues. Call Circle D and find out for sure
