Hello Mark-
I have mentioned before on the site that I was going to bracket my 20. I do not know if I am going to keep my word on that but for no other reason that fitting the boat in my garage and the added expense. Truth be told,I think its a great idea.
I wish I saved some of the pictures I had from my searches. I found many images of SeaCraft 20 CC with brackets from Boattraderonline and yacht world. Here is an aft picture of a 20 MA. This boat is still for sale on Yachtworld.com it was located in FL now in CT. I think it is a sharp and clean looking bracket:
