I’m not disagreeing with you but not sure which part isn’t right. Here’s a side by side of the 17mm heads vs Allen heads

So the friction disc seems to be a much larger diameter than the actual pressure plate or flywheel's intended surface ?

Your Allen key bolts do look like a fix...but not quite sure where the true blame is here.

But absolutely that would cause the problem you were having.

No, the friction disc and pressure plate are spot on

well the hex head bolts clear the disc...but from this side of the internet that disc looks bigger diameter than the PP friction surface

To me, a red flag would have been when installing the clutch the 6 point bolts hit the disc...aside from the noise the clutch would not disengage until enough disc material "self clearance" against the bolt heads

Does the clutch now work with the alan head bolts??

Did you put the disc on the input shaft and see if it would slide easily? I checked the stock pressure plate bolts and they have a 13mm head on them and if I remember right the flywheel bolts have a 15mm head.

Yeah those bolt heads had to be keeping the disc from moving. That looks way closer than it should be. That last post I made I didn’t see the pictures.

ALWAYS clean input shaft splines completely and apply a VERY thin coat of high temp grease to the splines. VERY little grease. Keeps disc splines from hanging up on input shaft

Clutch disc slides freely on the input shaft. It’ll be in the 30’s tonight so if I can get enough layers on I’ll stab the trans and see if I’m good.

Actually what I do is put a smidge of valve grinding compound on the input shaft and move the disc back and forth on the input shaft. Clock the disc one spline over and go back and forth again. Reclock and repeat. When you're done the splines will be polished, shiney and completely deburred.

Clean really really really good and then a very thin film of grease.

Sucksess!! Cold as ***** but I got it put back together and checked everything, it looked good. So, I threw the exhaust and driveshaft back in and busted it off. Bam! We’ve got a working clutch. I moved a foot or so forward then backwards. I gotta clean the shop out and maybe I can go for a test drive.
