Separated back, part 2

[James Baker]

I have used bolts only and had success.  I did let down the tension because
it was my first and the treble end of the plate was about 3 inches from the
back and scared me to death.  I inherited the old upright from another
relatively new tech (~14 years ago) who had pitch raised it quite a
distance.
