Sorry didn’t see the pic above, so is that a 3 start for a 650 that fits a dt3. I didn’t know they existed. More things to learn.

Yes it is a 3 spiral. Some of the XS650 parts were similar or identical to the Enduro.

Yep, this little gadget has brought my project to a halt for the moment. I saw a NOS enduro unit sell for $345 on on eBay and its gone now! I could not get the lock nut to budge but I was able to forcefully back out the rod adjusting screw out quite a bit. I hope this will be enough to allow the pressure plate to come up against the clutch plates normally. Dang, that lock nut is really stuck to the actuator body. It is not moving.
If I get binding while under load, I may carefully file down the threads in places to compensate for the expansion of the nylon threads. 

Send me a PM.
