I need some help on my top wood. I ordered the top ribs from ford wood but there is a 1/2 x 1 trough around the perimeter and I don't know what goes there. I thought maybe some sort of tack strip but there is a series of 1/3-20 rivet nuts in the groove that looks like wood should be attached. Any pictures out there that will help me get this right? I wanted to attach a picture but I couldn't figure out how to do it
