Diaphragm Pressure Plate

[jrvariel48]

I'm installing a fresh blower motor and looking to include a diaphragm style 10" pressure plate in my 35 coupe. I have a 1993 WC T5 trans with a hydraulic slave cylinder and old style(?) fork and shaft. I'm confused on which finger style diaphragm plate(flat or curved) I should use with the throw out bearing set up I have. I included pictures of the bearing set up. I'd also like to hear from some who have used this set up.
Thank you, Joe
