Alot of clutch company's provide their own new T/O bearing already attached to the new collar, because their finished height of the pressure plate fingers are different than a stock clutch, so again, that may indeed solve your problem by getting a 10mm taller collar....
In that picture you provided above, showing the old and new pressure plate side by side, you see where the T/O bearing has made its mark on the old one, where it engages against the fingers?...... just for $hit$ and giggles, place both pressure plates on a smooth surface, then can you grab a tape measure and stick it into the hole in the center of each pressure plate, and measure from the surface they are laying on, up to the fingers where the T/O presses on them, and see if you get the same distance on the old and new pressure plate... just curious...
