8 Bolt Crankshaft with C5 Flex plate?

1 Attachment(s)

I just realized that the LSA crank in my new motor is an 8 bolt crank. Therefore my stock flexplate wont bolt up to it. Does anyone know if you can bolt the torque tube coupler hub to an 8 bolt LSA/LSX flex plate? Based on the pictures I've seen it almost looks like it can be done.

RPM transmissions set me up with a custom flexplate they have made just for this application. Also from what I've "heard" a C7 flexplate will supposedly be a direct fit as well. Not sure if the C7 has an 8 bolt crank but I was told by someone that it works.
