From Mcleod Tech:
Yes the 75210 does come with the Long Style Pressure Plate in Kit form.
We don’t offer a (Pantera) specific kit in diaphragm form.
However, kit # 75212 ((*diaphragm pressure plate + dual friction disc*) $455.00 Direct) with the (Pantera) specific T.O. Bearing 16525 ($115.00 Direct) will serve you well.
