That is a picture of a Long style pressure plate and the Borg & Beck is "similar". Do you know what you have? Is it a Ford or GM T10? Are there any adapters in this set-up, modified components? God and the person who installed it are the only ones that know where the parts came from that cobed that trans into your vehicle. Pictures of everything including measurements of ID, OD, length of bearing, spline count and size of disc. Otherwise it is a shot in the dark and based on the response no else can provide the info unless you help us out.
If you chose not to provide the info here is a link to help maybe figure out what you need.
