Are we overthinking this?
I would have (ok, did) snugged it up, and it seated nicely. When I removed it(don't ask) it rewent back together the same way, no issues, no structure deformation by straight edge - probably means everything gave a little(like it should). Spar bolts then (make sure you clean out the powder coating) and snug them down.
Just my $0.02, worth what you paid.
