Seems the 1500 final drive is nearly a bolt in change, uses the axle, caliper and mount with a slight amount of grinding, same spacer on the axle, bolts up to the 1200 swingarm by enlarging the holes slightly. Also uses the 1200 driveshaft. I know my spare Valk final won't line up on the swingarm, already tried that. With a mostly completed bike except for the seat and a windshield, you know who asked why I want to start messing with it again with an essentially completed project. My only answer was "if I can do this, then it's not a completed project." Didn't buy it!

Have to see what costs might be involved then decided. Will it never end....
