If you do find the flexplate to not be neutrally balanced and decide to have the Jeep flywheel match balanced to the flexplate, be sure to have it done with the crank adaptor already bolted to the flywheel.

I'm planning this same swap. My OM617 didn't have any reference marks so I'm rolling the dice that everything is neutral balanced. May regret it later, but I don't think its likely.

Good luck!
