Pressure plate identification

In my junk... I mean, spare parts pile have a pressure plate with the following 
stamped on the back: Borg&Beck Co. Type-6 - 6 1/2 DS Leamington SPA England LL. 
 It has 3 groups of 2 mounting bolt holes with a dowel pin hole inbetween each 
pair of holes on a 7-1/2" DBC for a total of 3 dowel pins.  It has the finger 
springs rather than the coil springs.  Does anyone know what this fits?  I 
think my 948 flywheel has evenly spaced mounting bolt holes and only 2 dowel 
pins.  Thanks, Gary 1961 Bugeye
