have you poked around graflex.org ?
look under cameras on the main page and it lists the 2 different graphic view models.
with both the graphic view and graphic view II you can use modern film holders. i think the main difference
is the GVII has a graflok back, the GV doesn't ... i don't remember
the length of the bar, but you can use at least a 210 and longer if they are a telephoto design ..
you will need a recessed lens board for wide angle work, they are not too hard to find ...
the only drawback of that camera is it can not take a bag bellows + super wide angle lens ( shorter than 90mm ).
have fun with your new camera!
i had one for years ... and kind of miss it
