So I finally got the time and funds to get back to this project. The last two days I've been putting in a clutch kit and the re-built trans axle. Working methodically installed the new pilot beating and Sachs clutch kit. The clutch housing I first installed was from DC Automotive and had a 968 tag. The dimensions appeared to be good but I started having problems getting it over the ring gear. I had to do some grinding on the timing tab inside the housing and a hump where one of the starter bolts inserts. After several adjustments, everything clears and there's no binding when I turn the crack by hand. Part of the fitment issue are the solid motor mounts which don't allow the engine to tip for more clearance. I did eventually loosen the motor mount bolts and tipped it back with a jack stand. So I got the torque tube, trans mount, fuel filter and trans axle all bolted back in while periodically checking proper alignment by spinning the crank. Then I put the slave clutch cylinder back on and was bolting up the starter when there's issues. The starter is binding up on the ring gear and that's a problem. So I have to go back and drop the trans axle, pull the torque tube and clutch housing. I decided to try the original housing and once that's on, check the starter fitment before mounting anything else. Well that's the correct housing and I'm back putting the rest back on.
What I was able to accomplish before putting the pressure plate on was perfect spacing on the reference sensor. You have great access and can get a feeler gauge in there for the .8 mm gap. I also checked the speed sensor gap after bolting the pressure plate and ring gear. That matched up as well but the spacer must be on the speed sensor with this type sensor bracket.
So at this point I'm basically back to where I was when a sensor got fouled up and fell inside the clutch housing. The clutch did need to be replaced. The housing that was on the car was correct (I still don't know how one could tell the difference without mounting and testing). The re-built trans axle is in place and the clutch feels really good.
Now I can confidently return to the no start condition knowing that the sensors are precisely gaped.
I also glued in the windshield from my parts 944 and that looks nice.
