The other option is a 1/2” spring offset and 10” rear wheels. Funny enough, when you go up to 18x10’s or 18x10.5’s there are more wheels in the +15 to +25 range. And if you keep the A-body 8 3/4 that actually works. I’ve actually considered going back to an A-body 8 3/4 housing for that reason, I have 18x10’s now with a 1/2” spring offset and after some quarter lip and outer wheel housing modification's can go wider, but most of the wheels I’m looking at in the 10.5” to 11.5” range would work better with an A-body rear than they will with my current 68-70 B rear.
