That looks like a Borg and Beck type clutch to me. I would call Bob Mazzolini Racing and ask him about clutches. I got mine from him.

This is the clutch I fitted about two years ago. Car is driven daily and I have at least 100 launches on it at the local drag strip. I only adjusted it once, a few hundred miles after it was fitted.

Mick70RR the clutch your using is for a 143 tooth flywheel. His is probably a stock 130 tooth.

From the first post I assumed it was an 18 spline.

It is an 18 spline.

There's a lot of good info posted here.

First of all you have a big motor and need all the clutch you can get so use the 10.95" setup that bolts onto your 10.5" flywheel. Dollars to doughnuts that's what you have now.

Second if you want to minimize your pedal pressure the diaphragm clutch is the way to go. It'll cut your pedal pressure way down for the same clamping force. Your Centerforce idea was on the money, and you should be able to get a CF pressure plate because it has many applications.

Just buy the set in this link which I copied from up the thread:
http://www.brewersperformance.com/proddetail.asp?prod=MCDP1018 Be sure to get the throwout bearing to go with it and to pack the TO bearing with grease unless it is "lifetime lubed".

Back in the day my brother and I put a 3500# clutch in his 67 GTO and we were so green we put the throwout bearing in dry. The clutch was a bear to disengage, but no worries because in about 300 miles the throwout bearing had worn the clutch fingers about off. So he kept the disk and went with a lighter plate and that time we greased the bearing and it lived. Maybe all throwout bearings are sealed now, but we had to learn the hard way.

Good luck and ask questions if you don't know the answer.

Is there a Moparts Discount threw Brewer's ???

Am I on the right track now ????

Hello I have a 1970 Road Runner six pack car and a 1968 Hemi car, Both are four speed car. The Clutchs both came from Wayne Brewer! The one in the Hemi car has been in it for 12 years 354 rear and the six pack for around two years 410 rear.I have bad legs!also and they or not that bad at stop lights with the clutch push in!! Call Wayne!!

i just got the clutch for a 440- 6 cuda and i ordered a 10.95" kit from ram. you can use the 10.95 clutch with the 130 tooth flywheel and bellhousing. if you go to 11" you need the 143 tooth flywheel and different bellhousing, i know that from my last experience trying to fit a 11
' clutch in a 10.5" bell.

anyway the 10.95 disc from ram still was only 10 7/16 , i'm trying to figure out if they screwed up or its supposed to be that way

hope it helps a little

You will like that clutch setup.

Not if you want to decrease pedal effort. What you have listed is the Borg and Beck style. The diaphragm style will have a much lighter clutch for the same clamping force.
