305 12" Clutch

[AZKen]

My FLAP has the 12" GMC clutch kit with lever or diaphragm. Will either work? I believe Diaphragm is better if it is a bolt on. I have a 63 motor and 60 K1001. The one I see usually recommended on this site, 04-528, is a lever type. Please advise.
I guess a Diaphragm is easier to push but does not matter with my Juice clutch? Web says lever is stronger?

I almost always run a 3 finger or lever clutch. And I don't really think these clutches are all that hard to operate. Barry
