Maximum offset for rear of 1968 F-100 SWB with 17" wheels

[hornsco]

I'm getting ready to purchase a set of 17" artillery wheels . I'd like to make the wheel width and run 8.0 or 8.5 front and 9.5 or 10 in rear .My suspension is stock but will be lowered 3" frt- 6" rr If anyone is running a similar set up can you send some pictures so I can see what I'm getting myself into !! Thanks !1
