I believe the when & where info just helps the call-taker locate the firearm in its system or so it was explained to me. I think just a serial would be enough and the main fact to authorize the free part to be shipped (to the Armorer).
Edit to add: You, the owner's name & address is likely also wanted. Personally, I couldn't feel a difference between the 33564 "minus" connector and the Ghost "Edge" connector.
