Look again. You must fabricate the hinge pieces and spacers to off set the hinges in to provide for the fiberglass cowl thickness. These need to be drilled, deburred and countersunk before riveting them together with the side and bottom skin and firewall. Do make sure to trim the stainless steel firewall edges back before assembly to match the side skins. If you don't it will be very hard to do and protect your nice side skin edge prior to riveting and impossible after.
There are good reasons to do before cowl fitting. Attaching the hinges eliminates clecos in the way and securely fits everything for a good fit and alignment. The cowl part of the hinge provides support and positioning for cutting and fitting the cowl. I've done three cowls that way so far.
