Hi,
Anyone interested in having their SUs converted to ball-bearing throttle
shafts?  Anyone have experience with this procedure?  I'm thinking of
tooling up for the project.  I'm hoping I can defer some of the cost by
offering conversion service cheap (read at reasonable cost).  I'm still
in the thinking stage.  I bought a mini-lathe and things will never look
the same again.
Cheers,
Derf
