Go wing installation question for 74 Duster

I cannot answer about a Duster, but I do know that my 70 dart had a Go wing "Home Installed" with cut up sheet metal brackets. I planned on re using the Go wing, so I located a correct rear deck lid and brackets. On the Dart the rear deck lid has "Cutouts" for where the holes get drilled. I don't know about Duster, but I would assume something similar for Go Wing Duster deck lids. I suppose you could obtain the brackets and see if they work with your deck lid. It may not be correct though. Also, you may already have the correct lid, but I would assume you would have the brackets also if that were the case.
