How many teeth on your flywheel? 130 and it's 10.5 or 10.95 and 143 is 11 inch.No instructions came with either of the 2 WRONG pressure plates I have got from Summit. Another weekend pissed away, my car still on my buddy's lift...
I'm calling Brewer's on Monday since I bought my billet steel flywheel from them and find out what the correct pp is. I may go with a Centerforce after all.
I have never had an over center spring on it although it had a 3 finger Borg and Beck style pp in it when I installed the McLeod.
My left knee gives me some pain anyway, I think a diaphragm style pp will fix that.
I've been using centerforce for 20 years or so and would never go back to a three finger type.
