MT steel flywheels made in the US. No ring gear - you have to repurpose one off of a 2004-2012 colorado/canyon flywheel - either new or used.

Contact me if interested. US$385 + shipping.

Has anyone modified the Colorado hydraulic throwout bearing to accept another input, like an AN fitting?

I'd like to use my Wilwood clutch master cylinder.

If not, how are you connecting the T/O bearing?

Well, I went ahead and cut off the GM fitting and brazed an AN fitting onto the TO bearing pressure side.

Best part is that by removing the roll pin I can transfer the fitting to a new TO bearing if I ever need to.
