And there is still the trick of making sure that it is crossing
the bore with no vertical angle involved, which will increase the
apparent size. The rocking of either the spring calipers or the
telescoping gauges would probably eliminate this problem in use, but you
don't have the "feel" working for you with a too-short rod.

Slip a piston up from the other end of the bore, and let the bar ride on
that.
