I installed motor to trans and dropped it into my g body and I didnt realize there are 2 different bolt pattern flexplates. Most likely I have the 11 1/2 bolt circle and I need the smaller bolt circle. I have a yank pro converter if that helps and i was using the spacer. What flexplate do I need please? Only going to be in the 500 hp range with this LS3.

 

I would call Yank and ask, We did a Yank 4L80E converter and we had to use a flexplate for a 4l60e that came from a 5.3 truck engine.

 

If this one works for you, I'll sell it to you. Brand new in the box. $375.00 shipped. Not sure what shipping cost is, its a heavy sucker.

PM me if interested........

I took it to work and modified it to work, I should be good to go now.
