The base covers are more rare than the Islanders are, they were the first thing that would come loose, or removed by the rapair man and discarted. They just don't show up, and while a couple of guys have tried to reproduce them, the cost just outweighs what guys are willing to pay for them.
As for the housing frame, my website shows a new one for $240.00, I will sell you one for $190.00 shipped. This is a new one, in primer, ready for sandblasting and powder coating or just painting.
