Bass Pro and Cabela don' t carry the Copper John Pro II or Pro III...I ended up ordering a Spot Hogg Hogg-It sight...costed $179.00 (before taxes, broker fees)...ouch. Bass Pro and Cabela both gave the dimensions to their products. Somehow the Copper John site don' t have any dimensions for their sights. ??? I forgot...but there was a shop that sold the Dead Nuts Pro II for $80.00....I think.
