I had a pso w/same problem and did the same thing, but the
tuning pins were impossibly close to the screws.

the trick I found was to remove the carriage bolts after the
glue was set, counterbore the hole in the back large enough for
old upright plate washer, cut the bolt to exact length to be
flush or below the back.

With the nut in the back, I found I could even replace 1 screw
which was below the strings.

> lower the tension on the strings

yes. I'm a wuss and don't want to sweat. Too much tension and
you may not actually close the gap.

> remembler what size bolt

5/16 or 3/8 and as long as needed then cut excess.
