I have a 70 El Camino with an 18 x 9.5 rim with 5.5 inch bs. I'm running a Dana S60 with disk brakes. The disks push me out 1/4 more than stock and with loose body tolerances, I need a 6 or a 6.25 bs on my 9.5 to clear all around. With a 5.5 bs I have over a 1 and 3/8 inside clearance. I think your better to have too much bs as you can always use a small 1/4 inch or less spacer. I will be sending my wheels out to get re-hooped.
Hope this helps
Pete
