Dave,
         That's an interesting thought and a possible resolution to the=20
crisis but it doesn't answer if anything could or should be done with a=20
warped plate. I may go back to the call I had last night at my own expense=
=20
to see if the glide bolt adjustment will work. I don't mind eating a little=
=20
for my own education. I still wonder 1) could this have happened some time=
=20
after manufacture and 2) If not, why was this ever sold in the first place?
