Will a 11in clutch work with a 12in pressure plate and a 12in flywheel?

Thanks
Ben

The 11 & 12 " clutches fit the same flywheel(14" diam, 168 tooth ring). The12" disc is larger , & the press plate is larger, & also scalloped to fit the same bolt pattern as the 11" setup.....I dont think I would mix the pcs tho, go all 11", or all 12" on the parts. good luck, crazyL

Let me see if I am getting this right. So I can buy a 11in pressure plate and clutch and it will bolt to a 168t/12in truck flywheel?
All I am wanting to do is convert my clutch from a 10 spline to a 26 spline. I was thinking that I would need to get a 11in flywheel, 11in clutch and a 11in pressure plate to make this conversion. Do I have it all wrong?

Thanks again

Yes, you can bolt an 11"clutch setup on the same flywheel where the 12" came off. the bolt pattern is the same .....crazyL

Great!!! So I don't need a new flywheel, just a 11in clutch with a 26 spline input and a 11in pressure plate.

I wonder what came with this setup from the factory????

Would anyone know?

Thanks again
Ben
