[Healeys] Rear Wheel Cylinder Retainers

[Bob Spidell]

Thanks, Simon!

But, it appears #1 (Michael Salter) and #3 (from John Sims) contradict 
each other; what should be the 'tie-breaker,' #4 from the late, great 
Dave Russell doesn't address the orientation of the two.

My gut, and common sense, says the flat plate--with the notches--should 
go against the backing plate, but I've always installed them the other 
way around. Would really like to get this right, though I think things 
work OD either way.
