I had about 150 passes on mine at last inspection but dont turn much over 6K,I say yours is seeing quite a bit above 6K. I wonder if the extra harmonics of 4cyl shortens life of pilot bearing,throw out bearing.etc
Use to get BCA bearing to use w/long style press plates,were looked up for early 60's GMC truck that had the big GMC V6 w/long style pressure plate if remember correctly took bearing off the (don't know name of part) housing maybe well any way bearing presses on it and it goes in clutch fork and press back on regular chevrolet piece.
One in my car now is Ram.
