Rear discs

["Angela Hervey-Tennyson & Peter Westcott" <toobmany@bigpond.com>]

Page 124 of More Healeys gives more insight.  Essentially the Dunlop 4
wheel discs (same setup as MGA Twin Cam, Mk II Jag) were listed as options
for homologation and  "...really only available for works cars..." but that
isn't to say some escaped onto very special road cars ie: those for testing
or publicity purposes.
