I know it's not my money but I'd call Rob Youngblood or Cale Aaronson and see what they can do for you. You need a Long style pressure plate. I have been using a B&B/Long for years. When it's used up I'm switching to a Long PP.
BTW, Cale may still have some stuff to make you an adjustable B&B/Long cover. blackmagicclutches.com
