[TR] Caliper O-Ring

[Wbeech]

OK, I know we are not supposed to split the calipers but they were really
old and nasty on this TR3B, I had to scrape the rust and crud out of the
groves along with the bits of rubber seals. 
 
The re-build kit does not include the O-Ring between the calipers, TRF does
not sell them, guessing that Moss does not either as they are not listed.
Does anyone have a source for these to little o-rings?  Maybe Mc-Carr?
 
Thanks,
Bill B
