What prop shaft setup??

With a 2 piece shaft, where do you mount the center bearing?? Should it be on the straight line between the diff and the motor, or should you keep one section as an extension of the diff flange with 0 degrees angle, and let the front section carry all the angles? This is with a bike engine and a solid mounted IRS diff.

I'm running a 2 piece Bailey Morris driveshaft setup with a center carrier bearing. I had to fabricate my own cross member out of 2x2x1/4" Aluminum. The rear diff to center bearing driveshaft run is pretty darn flat and parallel to the chassis rails. The output shaft to center bearing is at a slight angle which mimics the output shaft to reverse box angle this setup replaced. I bolted the driveshaft at each end and I found a happy medium in the middle of the driveshaft tunnel as well as keeping the driveshaft level. The engine is rigidly mounted as is the rear diff. If it was a solid axle Mustang with an engine that rocked back I would have positive/negative angles cancelling each other out. Not much flex in the Megabusa.

Thanks, Hank.. that's what I needed to know. Is the slip joint on the front or rear section of your propshaft, is is your motor mounted so that the flange is vertical in the chassis, or does it slope back slightly? Cheers, Evan.
