The 410 should have a smaller frame than the 12 gauge. For $100-$150, you should be able to get a whole 410 Champion.

Iver Johnson did use the 'EXCEL' trade name for some hardware store guns. However, the guns are earlier than the more common Iver Johnson Champion model and Champion barrels will not fit the EXCEL marked frames. You will have to keep searching the internet, eBay, etc, and hope that somebody puts one out for sale. sales@countrygunsmith.net
