I also thought about the crossmember from a 115/107 but am not sure how that all is in relationship to the wheel centerlines. The front pully on the 617 appears to be right on the centerline of the front wheels. Clearing the front pan is iffy but probably very good if a front steer with rack and pinion is used. 11" brakes are desired as a minimum with the 26 to 30" diameter tires I want to use.

I believe I can put a 123 cross member under the motor mounts and get places for the stock motor mounts and the motor shocks to bolt to.
