my couple pennies
is you cannot beat South Bend and their service rep Peter Pyfer
I had a CON-O that crapped the bed after 75k mi/14 months and he was on the spot with a full replacement at no charge
I up graded to the CON-OFE at that time and it has proven to take the abuse I give it
Plan on spending about $850....about on par with the rest and for that you get an entire kit....single mass f/w, new f/w bolts/ friction disc and press plate w/new bolts/ align tool/new Throw out brg and kevlar pilot shaft brg.
You left leg will not believe the ease of this unit
