TOPIC: Need help identifing model year on this Cub Craft?

Hello,
Just picked up this boat. Its a Cub Craft model #20 Bear Cat Deluxe. From the tag it looks like it was mfg'ered by American Fabrication or something like that out of South Carolina. Its smaller all fiberglass boat, but I cant find anything on the internet about Cub Craft boats or there history. Any help would be appreciated.
Thanks
Andy
