You might check an off roading store or a store that sells VW & dune buggy parts.
When I was building desert rails & sand rails I used them on a lot of the seats to secure the seat covers & they worked great & I picked them up at a local VW & off road shop. They we're alot cheaper then a boating supply house, You may also find them at a material store.
Nic the ones I used we're real easy to install, the snap side that you will be putting on your canvis you will have to use a plier looking crimping tool
which is available at wally world or the material store. And the snap part that will be on your trailer all you will have to do is get the proper size of screw and put the screw threw the center hole in the snap, just be sure that the screw seats down in the snap so that the other side of the snap will be able to snap to it. ( I hope this makes sense to you.)
