and George, there is no splined shaft, but the pins can move inside the
pucks. There 6 pins total. I don't have an e-mail address for Marcotte,
but do have a phone and fax number, so will try and contact him tomorrow by
fax, as English is his second language and having spent my life on the farm and
in heavy industry, my hearing is shot and I can't understand him on the
phone. I haven't had a chance yet to check the end play.
