10% done, Steiny, and only 90% left to go! :D

Who was it that mentioned Dante's 9 layers of Hell....?

Ta-da, it's done.

Some more tips:

-Leave the transmission mount disconnected while you put on the starter, speedo cable and especially the shift housing.

-Put a couple of drops superglue onto the shift housing gasket the night before or use liquid gasket

-Assemble shifter in-situ. Slide in from top. Grease it with something sticky (i.e. wheel bearing grease) so things don't fall apart. Use the three screws to hold the plastic doohickey in place, then crank down on the (self-locking) nut for the shifter. Remove the screws, then put the cover on and tighten it up.

-Make sure your guibo is on your transmission before you put it into the car.

-Don't bother with sliding the yoke off the driveshaft. Just disconnect the two m8 bolts that hold the drive shaft in place and the rear four bolts at the diff. Disconnect the three bolts on the guibo (driveshaft side) and let it dangle on the handbrake cable.

-Buy a 4-2-1 header and downpipe. The alternative sucks to reassemble.

Car shifts butter smooth and the transmission is perfectly acceptable noise-wise. Still louder than all my other cars, but there you go. I'll stuff some padding under the center console and it should be good. Clutch feels brand new (because it is...)

One thing the car STILL does after 3 transmissions and two pilot bearings, plus a new clutch, throwout bearing bla-bla is the annoying whirring noise at idle if your foot isn't on the clutch. I suspect it's due to input shaft play on the transmission(s), but who knows. It's much quieter than it was, but it's still there.

Cheers

Awesome, Steiny! As for the whirring noise, I think a certain amount is "normal". Most of my various spiders have done this to a certain extent, although for some reason, my current '71 is quiet. Let's hope it stays that way... :wink:
