What would be the symptoms if the disk is in backwards?
Loud noise when you push the clutch pedal at a standstill, the springs on the center of the disc will be hitting the flywheel bolts

Have you checked to see if maybe the trans input shaft isn't pressed against the pilot bushing /bearing? Maybe the pilot isn't deated all the way. That would cause the condition also. oops i see that has already been suggested.

This may or may not help but i'll give it a shot anyways. My 70 Duster did the exact same thing over the last year. When the car was off, the 4 speed shifted gears smoothly and everything was great. Running however, it would grind going into gears and sometimes, the grinding was so bad that I couldn't get it into a gear unless I shut the car off and put it into gear, then restarted the car. We tried everything you could think of in terms of messing with the linkage, pulling the trans to check the output shaft, etc. Finally, I came across an article of a guy with a similar issue and it turns out, it was the pilot bushing - it had a microscopic crack that we couldn't see with our eyes when it was installed in the car however, when we removed it, it was easy to detect. We have since replaced it with a new pilot bearing (NOT the original brass bushing) and since I've replaced it, i've driven it a good 100 miles and it works flawlessly. It sounds like you've checked a lot of the other stuff w/ no luck. Maybe worth a shot to check the pilot bushing?

Definitely something I will check when I pull the trans. Thank you! Do you have a copy of this article? I'd like to think this isn't the issue as everything is new but like I've posted a lot of things have been wrong thus far
