Tim, et al,
I believe you were referring to me;   One list member had one
professionally installed by a trans.

 `Matter of fact, I'm sure of it... I bought one to compliment my 1.6l
to 1.9l TD swap. There was no way to control the van. It had a mind of
it's own. It was installed properly but with the torque of the 1.9, you
steered the van with the throttle. Power on, move to the left. Power
off, go to the right. Neutral throttle, straight ahead... I had it taken
out and replaced with the original components.

My advice: save up for a Syncro differential.
