Default Halp! Clutch disc installation

On a 69 350 w/ M21(?) which side of the clutch friction disc goes to the flywheel - one side has a protrusion on the spline, and one side doesn't, and I can't seem to remember (crs disease, I recon!)

Thanks in advance!

The springs are recessed on the flywheel side of the disc and the hub will face the pressure plate {transmission side}. Try it against the flywheel and it should become apparent.....

Default Thanks y'all!

Yeah, it was obvious, once I tried it either way. (My last clutch job was on a '95 LT1 Vette (last summer, actually) with the ZF6 and on that one the disc could be flipped, as I recall.) Anywayz, thanks for the quick response! Now if I could just stab the trans back into the pilot bushing...(being a pain - alignment tool not withstanding).

I made up some alignment studs by cutting off the heads of a couple of transmission bolts and grinding the ends like a bullet. Insert them in the bellhousing and make them long enough so the tranny will hang on them before it touches the pilot. Then you can push the transmissiion in knowing it's pretty straight. Good luck with it
