Clutch Differences

I just bought my 77 F150 and it needs a clutch, I'm seeing two listed that look verry different. How do I know which one I need for my truck?

One is a long finger the other is a diaphragm. on a '77 you probably have an aluminum bellhousing so you can use either one. a quality kit of either design will work fine.

So both will work with the existing flywheel?

Yes and I want to say I seem to remember the multi finger one (L/H one) is easier (clutch leg wise) and the 3 finger one (R/H) is heavy duty.

With most diaphragm clutches you're supposed to remove the assist spring under the dash to offset the softer pedal.

I'm not sure one is really better than the other. the biggest thing I can see is the diaphragm clutches usually use centrifugal weights to increase pressure, that's better for high RPM applications like a car than for a low-speed heavy pull a pickup.

Which ever style you choose buy a NEW CLUTCH an not a reman.
I can just about guarantee a reman will chatter.
I prefer new, Luke clutches are my favorite.
