Universal Seat Bracket Use

The 69 Dart I recently picked up was an original bucket seat car but has a bench in it, I was able to find some 69 Barracuda seats but there were no seat brackets. I don't really know what the brackets are supposed to look like and wanted to see if anybody had used these from Summit, it looks like with some minor modifications they could work. Any thoughts?
