Yes... Basically, they were just a few thou' more than the original,
but big enough to be a good "fill" for the raceway. I suppose I ended up
with about twice as many bearings as the original, because the metal bearing
holder was not in use any more. This means that there is less "slop" as
there is twice as much support as originally, and correspondingly less wear
as a result..
Good luck in your efforts es 73
P.S. I think I'll copy this to the reflector...Maybe someone else may find
the info usefull..
