New 408 for the Flyfish
I didn’t read your whole post but will later. As far as the convertor being tight in the back of the he crank been there done that. And so has a friend. His was an eagle Crank and mine was a K1 crank. I didn’t catch mine till I hurt the thrust bearing but it a simple fix with a flapper wheel (sanding wheel) on a small die grinder. I honed out my pilot hole in the crank under the car. Took about five minutes and a couple of test fits. If you need a picture of the sanding wheel I used let me know
