I recently purchased some Cruiser Corps rear jump seat covers for my '78 FJ40. My question is that they don't come with the wire installed around the edges like my previous ones. Do i just put the screws through the doubled up vinyl around the edges are make cuts in the ends to install wire? Wasn't sure if the vinyl itself is strong enough once you pull the vinyl tight. I've searched on the forum and haven't found a good installation tutorial or video on youtube. Appreciate the help in advance.
