Oh, hinges are new? They do have some play but shouldn't be too much. Can you hold the end of the door and lift up and down and feel movement? Otherwise, even new hinges with a striker sitting higher than the latch will lift to close. Do the doors line up when shut? Sounds like striker is close to position but hinges are set too low for door hang. Loosen bolts on cowl side, try to lift door up past the striker until it hangs down buy higher than now. Or, to re-explain that, if you remove the striker you'll find door shuts too low.
I thought FBW may have faded away to nothing by now. When Pete left, there was no one left with knowledge or interest in the hobby, just his Mrs trying to make a quick buck. Their website hadn't been updated in years, when I checked. And corrections went ignored and not replied to. I don't like when shops have blatantly incorrect and misleading information. And when they ignore corrections because they'd rather sell items at any cost, I avoid at all costs. Very different to 10-15 years ago.
