I'm doing a clutch swap and I've had a hell of a time getting the reference sensors out and broke one off in the sensor housing. This is preventing me from getting the bellhousing off. Any suggestions? How hard is it to remount the sensor housing correctly? With the way the engine sits right now, marking the underside of it is pretty much impossible. I'm also having trouble getting an allen wrench down to the bolts holding the sensor on.

It is is not that hard to remount the sensor right. It just takes a little time. Gap is about the thickness of a penny.
