Centerforce Dual Friction installation question
My motor was pulled from my car last week and I am going to go tomorrow the engine builder and watch him tear it down to find out what happened.
Anyway, I am going to have a Centerforce DF installed when the motor is put back into the car. I have been told to have an adjustable pivot rod (??) installed as well.
What is this and where do I get one? I am ordering the DF from Summitt. Will they have one?

Adj pivot ball/stud is what you want and yes summit has them. Just make sure whoever puts the clutch in follows the orange card that comes with it.

I installed mine last July, and fevre is right - you do need one and I would get a new throw out bearing as well just to be safe. It is an easy instal but as Chris stated follow the orange sheet.

The Ball stud is what the shift fork pivots on. Screws into the Bell housing from the back and comes in about 2 "s from the T.O. Bearing. Also recommend you use Locktite on that Ball stud as they break loose fairly easy.

The clutch fork will be too far back and will hit the tranny and NOT dis-engage. The stock Ball stud is too short by 1/2" I think

What is it? Check out this diagram:
You should be able to see the clutch fork pivot ball in the top left part of the diagram.
Check out this thread. Discussion of the same problem and Steve Straus posted pics of 2 different GM size clutch fork pivot ball studs.

Yes, Summit carries the adjustable models. They are sold under the Mr Gasket name, Summit's part # is MRG-3855G
or Lakewood, LAK=15501. These 2 are pretty much the same part.
If you do not use the adjustable part you will have to push your clutch pedal all the way to the floor to shift gears. There will be no adjustment left on your clutch rod to adjust the pedal higher. You will turn on your bright lights every time you shift gears! :lol: You will be forced to dream up bubba fixes like extending your clutch rod, because the correct fix involves pulling your trans and replacing the clutch pivot ball which is a major PIA, so I encourage you to GET IT RIGHT NOW!!!! :lol: good luck! :) MJ

Re: (MNJack)
Here's another post I made on the topic. Actually used pictures of my own in this one. I'd find someone to weld the adjustable ball for you.

1970LS6,
I used the stock set up and a Dual Friction clutch set up with NO problem as of yet. Shifts fine, goes into gear fine, not a hard pedeal either...
