Gas vent tube hole size and location

[Puzbie]

Happy father's day a day early for those dad's out there!

Does anyone have the size hole needed in the trunk floor for the fuel vent tube?  Also does anyone have a reference distance from the closest body plug hole?  (are they the same size? it looks a little smaller.)  As with everyone else who has a new floor, that hole is missing.  Sadly didn't know this until after she was painted.

As always thanks for any help!

 not sure is this is any help  heres a pictures of unrestored  69 trunks ,

the vet tube grommet is a different size to the nearest body plug i think,

cant really help on the size hole ,  the hole i drilled  in my  repop trunk floor  31 years ago was a guess , & used a generic grommet at the time , back then OEM was not that important to me
so  dont think there is any point  me measuring  mine  i've now got a repop groment  although not sure if its the same size as an original or even the look of a original , ( bought 20 plus years ago so cant be sure if that accurate )

Yes the two holes are a different size
Vent hole is smaller I think
Can not say how big the vent hole is
I just used a drill to get started and then a die grinder to keep going around till the vent plug fit nice

I did keep my old floor at the time to get the proper location but did not have an actual number for the hole size
