Since I got the rear and engine mounts buttoned up, I had a chance to order the driveshaft. I ended up going with a company an hour or so away, Driveshaft Specialist Inc. Brent was able to find exactly what I needed in his parts bin to mount the Subie diff. to the Chevy transmission and work with the lengths I provided.
The final seal-to-flange distance ended up being 19.75″, so it’s a pretty tiny driveshaft as you can see compared to my (almost) two year old daughter. I ended up going 2″ diameter, but could have gone thicker given the diameter of the U-joints. Either way, the 1/2 true critical speed on this shaft is over 26k RPM, so I should have no vibration issues. Yoke slip is right at 1 inch.
