Fin set ups
a true twin keel swallow tail? you could make some out of plywood. they should be 7- 9 inches and shaped like half of the tail as in trace the shape of the tail onto a piece of ply wood then cut them out.
When shaping a fish most shapers trace the keels into the tail so it should work the reverse way around.
Show some pics?
You could use photobucket to add photos and other similar websites. Pretty easy to use however im not really the guy to ask for that sort of thing, if not anyone here sorts you out on here id say go to swaylocks general discussion or search engine.
Thats where hundreds of professional and amateur shapers gather in discussing boards and fins.
I will say though if its a narrow swallow less fin area, unless its to be surfed in bigger waves. There are guys now using large twin keel fins on big guns and semiguns as they can handle a lot of juice.
IE at mavericks etc.
I love keels such a unique feeling of drive not to be matched.
This is the a good website to use to upload photo https://imgur.com
