is the Hole Spacing for Repro 03A4 mounts the same as the original Redfield mounts? I am having an A4 assembled and my choices are either buy whole repro unit (mount and rings) or use an original Redfield Jr. mount and order repro rings.

Any suggestions on how to proceed? Source of repro is New Zealand. Is there a domestic source other than Gibbs? They will only sell to dealers.
