I thought on the U20 they were ALLENS not BOLTS - at least BOTH the 5 spd trannies I had.

Actually, yes they are Allen head machine screws as opposed to hex head machine screws if you want to get picky about names. Regardless, make sure you use high quality pieces if you don't have the factory ones as you don't want these to shear. That would not be good.

Right, once again chinese parts from Autozone would be a bad idea....
Blue loctite is a good idea..

I have the correct Allen head machine screws thanks to JT. Now to install his lighten flywheel to my "original" 67.5 motor in preparation to swapping back into my car. I use blue locktite.
Thanks again to JT

Is the M10x1.5 just a U20? Manual lists M10x1.25? Is that R16?
