Per Talley spec sheet for Tikka mounts, distance from top of receiver to bottom of scope tube, same for 1" and 30mm mounts:

Ex-Low = 0.400"
Low = 0.500"
Med = 0.600"
High = 0.700"

Per posts above, the "Modification" removed approx 0.100" of material from the bottom of the mount allowing the "ears" to straddle the dove tail on top of the receiver. Shoot me an email address via PM, I will email the file to you.
