both 10.5 and 11 inch pressure plates use the same mounting holes, right? So, I could use either size with a particular flywheel-just match the clutch spines (26) to the T5.
It's starting to be clear now; thank you all for the advice.
I would have to say no, the bolt pattern is different. If they were the same, you could put an 11" clutch on a 153 tooth flywheel, and there is no application that I'm aware of (with 2 piece rear main seal) where this is the case.
Just to be sure, you could take a tapemeasure to the parts store and compare a 10 1/2" and 11" pressure plate...
