17" ralley help needed

[Thumpt]

I would like to purchase a set of 17" 66 ralley wheels from wheel vintiques.
I want to run an 8"rim on the front and 9" on the rear 555 nitto 245/45 and 275/40. The wheels come in an 8"x 4 1/2" bs and 9"x 5"bs. They will go on a standard 69 camaro that have had the guards rolled.Will these fit ok or will the bs need to be customised.
Thanks for any help you can offer or a picture of these fitted already if anyone has one.
