When I put the dog-leg 5-speed into my 1200, I had to get a driveshaft from an automatic tranny.
The drive shaft splines on the dog-leg 5-speed is the same as an automatic tranny if you can find one. Unlike most driveshafts that have replacable U-joints and therefore the front yoke
is replacable, the 1200 U-joints are not replacable, they are welded. The dog-leg 5-speed is a heavy duty trans and produces more friction and uses more of your horsepower that the
regular 5-speed or 4-speed, although the most think the tranny is worth it. You get nothing for free, you have to trade HP for better reliability. I think the 4-speed was very reliable. I
put over 200,000 miles on mine and never had any problems. I still have the 4-speed if anyone needs it. I also have a 4-speed with fewer miles on it.
