I have read through the faq and have yet to answer my question. My 3 speed in my 73 fj 40 on 37s shutters when I am letting out the clutch. I am going to be pulling my tranny and t-case this week to address issues with the t-case but if it is my clutch that is causing the shutter what is the best clutch to get? I know i can get the 3 finger sachs clutch from a buddy for $190 but is there a better clutch out there for it?

Go OEM. Resurface the flywheel while you're there, since that usually needs to be done too.
The later style diaphragm clutch is actually a better product. However, along with it, you need to change the flywheel and throwout bearing, etc.
SOR has the complete kit for approx $350.

The shudder is caused by the too tall gearing w/ a 3speed and 37" tars.
If the gearing was shorter, then there would be much less clutch slipping when starting off.
FWiw, an SM420 transmission is an easy swap into a 3speed truck. Gives the same top 3 gears, but with an added granny gear to get those big tires rolling away from a stop sign.

I used the finger clutch from spector and it works perfect. i think everybody han an opinion about the clutch but just replace it with the same set up and you will be fine.

Where do you live Winkle?
Does the SM420 need an adapter? Ive got a chevy 327 with the stock 3 spd tranny. Like to have the SM420 though.

I doubt you'd use 1st. gear of an SM420 on the highway, even with 37" tires. BTW, I still have my one-and-only HD 3 spd. 3 finger clutch (pressure plate and disc, new in the box, closer to 2,000 lb. clamp load compared to 1200-1400 lb. stock clutch), PM me if you need a bargin basement price on this puppy.
