Dont know for sure what you mean, but:

-the adapter plate as it is now, will have the center of the tranny shaft at the exact same place as the center of the crankshaft.

-Dont want to modify the tranny shaft either, thats for sure. I am gonna make the custom flywheel that way, that i dont have to adjust the crank or the tranny shaft.

No more news yet, to busy with a lot of things, and now 3 weeks on a holiday!
So August or September pictures of the adapter plate, after that fit the package in the 190 engine bay, and see if its doable.

Then, when i know its doable, i'm gonna make the flywheel (lot of work i suppose...)
