As I ponder about this more though, I'm beginning to wonder if this much angle on the short shaft puts me in CV territory, possibly killing my "off the shelf parts" goal.
Rear shaft section is currently 2'6" from center to center if anybody has any bright ideas. I could wire EDM out a "slip yoke eliminator" with a flange to fit on the rear slip shaft, then maybe run a k5 rear shaft (dont know length) if they come with CVs... I don't mind having to shorten and customize the front section, as it's unlikely that it will get injured.
All my joints are currently 1350s. I guess it wouldn't be the end of the world if I had to carry a spare conversion joint in my glove box if I could make a k5 shaft work..
