Any news Rick?
I'm sure you already know that the 4 cylinder version of the car had a straight shaft out the right side of the transaxle to a hanger bearing. The inner CV joint was on the outside of that bearing.
You can see it in this pic of the ForkenSwift's motor compartment:
The problem is that there's not likely enough room for the sprocket that size (clearance to the back of the engine). So if you were to do it, you'd have to do reduction somehow. Oh, and relocate your motor somehow.
Just thinking out loud.
