p.s. forgot to mention that I need to have some straps sewn into the bottom of the side curtains in order to lash them down to the gunnel.  I have a problem keeping the rear snap on, as you can see in the pic.  I have a problem keeping them all on with just the side curtains on (no back curtain).
 
p.s.s. Don't laugh at my ugly blue seats.  They have been replaced.
