Now I've read the whole thread. It seems the OP does not actually have the tranny bolted in yet, so it's all conjecture at this point. Hopefully things will work out when all the parts are actually assembled.
Ok so I have a picture.. I don't have the transmission bolted in yet but judging from the differences between the 4 spd fork and the 3 spd fork you can see that the 3spd fork is sitting on the bellhousing and pivoting on the boot rather than the ball..??
I hope so... because of right now it has about 1/2" before it lifts off the ball.
I'm sure I will figure it out.!

HELP!!!
Ok so I read through this and am still unsure what I should do...I have a 3 speed 1968 transmisson & a '75 2F that I picked up. I have no idea if the 2F had a 4 speed or 3 speed (if that even matters) I used my old finger style setup & it slipped even though the disc was in good shape. My guess is because the flywheel is made for the diaphram style. So now I ordered the diaphram style clutch kit (PP, disc, to bearing, pilot bearing) So the way I see it I still need the different fork & TO bearing hub to make it all work. Does that seem right?

Pretty tough to simply go off what you have provided here in text as to what you should do next.
Did you take any pictures of what you have when you had it all apart?
Perhaps you could share some if you did.
Whew, Poser I thought I was going to be responding to a 4 1/2 year old post, now it is only two years old
.
My 1970 has the three finger clutch (CCOT kit, throw out bearing sucks and is already noisy, 7,000 miles) and a 3 spd on the floor. So to convert to a 4 spd, I would need the bell housing, keep my fork. Now I don't need to convert my transfer case (although it is completely rebuilt), I can use the 4 spd transfer case, correct? What happens with regards to the e-brake setup and driveshafts? Seems I have read that the rear driveshaft gets shorter and the front longer. Does that mean when I shop for the 4 spd I need to try and get the driveshafts as well and then am I good to go or do I have more modifications in store? Thanks. It is really hard to find parts down here. And really expensive to ship them down from the USA.

are the F flywheels heavier than a 2F FW?

The coilspring FW is marginally heavier than the diaphragm FW, 44 vs 42#, IIRC. The 44# FW has a much higher polar moment because of the concentration of mass at the outside edge. That is a good thing for 4-wheeling, makes the engine slower to rev & un-rev (stall).

Someone mentioned the diameter of the throwout bearings were the same, but in my case with a 1971 FJ40 the diameter was different and we had to use an early FJ60 bearing retainer and clutch fork to make it work.

Stop calling it a "FJ."
Hi all,
My memory is that the throw-out bearing used with the old style "3 finger" clutch is smaller in diameter than the T/O bearing used with the later diaphragm clutch.

Alan

Bumping this….
Can I use a 3 speed flywheel and pressure plate with a 4 speed clutch kit and 4 speed? I’m swapping engine and transmission on my ‘73 and have the engine, bellhousing, and 4 speed but don’t have the 4 speed flywheel/PP
Cheers

IIRC the only common part to the two systems may be the clutch disc itself, but I may be wrong. The clutch disc part number changed in 4/73 and again in 10/76, but the 3-speed transmission to 4-speed transmission change was in 1/75, and the clutch pressure plate changed from the 3-finger clutch in 8/74. So the clutch disc part number stayed the same over the pressure plate transition.
Ok, so if clutch disc and flywheel are the same thing, sorry for my lack of knowledge here, then I should be good to do that. I bought a 3 speed clutch kit from Cool Cruisers only to find that I am now going the 4 speed route. I will be returning the 3 speed clutch in favor of the 4 speed kit. There is a local clutch shop that can resurface/clean up the flywheel...
thanks, @4Cruisers

I ran into a similar problem with a confused customer working through an even more confused mechanic earlier this year.
The best advice I can give you is to NOT RETURN ANYTHING until you have everything in front of you that you think you need to do the job, THEN POST PICS to get advice from the collective.
Odds are you will end up buying a newer flywheel. Better long term prospects.
Thanks for the advice! I’ll keep the thread posted once I get parts rolling in
