I was on the fence between using a 915 or a 901 style box for my 3.2 six conversion until recently where I read a comment from @ClayPerrine that the 70-71 911 (911/01) box was set up with the pull style clutch.

What I have in hand for my conversion:
- 911/01 box
- Three side shift 914 gearboxes
- Various gear set ratios to have fun! (IMG:style_emoticons/default/driving.gif)
- 100mm coarse spline output flanges to go with my 944 CVs

My plan was to use:
- Stock 3.2 flywheel clutch assembly currently on the engine
- Get a 70-71 release bearing
- Get a 72(?) clutch cable that would be straight pull (no cable pulley)

I was going to use the 911/01 bits, flip the R&P, reset the pinion depth, use complementary 914 side shift trans cover, shifting, etc

What I think I am undestanding from this thread linked below is:
- The pull clutch setup works well
- Yes, it can be tricky to get the release fork mating to the bearing upon assembly
- I should not use the 3.2 PP as it will pull the fork pivot bolt?
- I should use a 2.2 PP?
- What disk should I be using?
- Does this simply bolts on the 3.2 flywheel?
- Is the clutch pivot shaft/arm at the pedal cluster different than 914, should I replace it? I just rebuilt my pedal cluster.

Any inputs appreciated (IMG:style_emoticons/default/beerchug.gif)

My experience…
3.2 with KEP adapter and stock 914 trans.
-Uses stock 3.2 flywheel and has special bolt on ring that adds 228mm bus clutch. They recommend there stage 2 kit.
-This clutch is harder to push than stock.. Some people have no issues with it. I also have a v8 914 that uses a stage 3 clutch which is even worse than the stage 2. I am also selling the v8 car and that is one of the reasons I am selling it. Note KEP also sells a 228mm flywheel instead of the ring that also works with there clutches.
-If it’s a stock 3.2, 1st is worthless and 2nd is too tall to use as first without slipping the clutch. Not a problem with a hopped up 3.2, 3.6 or v8.
My current setup I used with my 3.2. All stock 915 trans for a 3.2 with Martin Bott 916 kit. Clutch is super easy to push. Like butter. There is a return spring on the pedals and an omega spring on the trans. Also the gearing was designed for the 3.2 so all gears are amazing in town and on the freeway. Downside it’s super expensive.

I was also planning ahead with the 915 trans for future 3.6. I recently finished the 3.6 and sold the 3.2. The 3.2 was awesome with the 915 in a 914, but the 3.6 with a 915 box is beyond amazing.
