Install the snaps? Are you sure he didn't misunderstand thinking that you wanted to
add a bow cover to your boat and that they would need to install the male sides to the hull? I would have thought that the canvas came with the snaps pre-installed.
I think the canvas is ordered by FW from Great Lakes Boat Top Company - 15 Quality Circle, Vonore, TN 37885. 423-884-6761.
http://www.greatlakesboattop.com/My dealer had a replacement top and boot shipped out from there and it fit like a glove. AFAIK each piece of canvas has a code for re-order / replacement. If you need me to find the tag I can look, but I don't remember seeing one on the bow or cockpit canvas.
(edit) Oh sorry forgot you had the 220 my tags won't match anyway.
