[Mgs] MGB brake caliper seals

[Matt Trebelhorn]

I was rebuilding the calipers for my B this weekend, and managed to  
mangle two of the metal rings that retain the outer seals.

(I would not have done so had I checked Barney's webpage first.  The  
method on this page:

works brilliantly.)

My question: can the metal rings be bought separately?  I don't want  
to waste a rebuild kit if I only need the metal rings.

One cool thing I figured out and wanted to pass along:  u-bolts from  
the rear axle have the same bolt spacing as the calipers and make a  
good stand for holding the caliper while painting it.  (The caliper I  
did rebuild is now grey; no red/yellow/purple etc. for me)
