420 rail heighth

Mike,
The rail height for the 420 rail is 3.200 inches from the pad mounting
surface to the top where the roller contacts it.The approximate rail
thickness of the roller contact surface is .812 inches.These measurements
were taken from new old stock parts but, as with any forgings, there
is some error in measurement.I can also provide measurements for
the bottom rollers based on NOS parts if someone wants them.Hope
this helps,JimAnderson
