18" Wheel help

I completely agree that sometimes you have to find ways to make things work. And sometimes we get tunnel vision and forget to look for other solutions. So wise words.

But in this case, I think that is an extreme solution. As I understand it, the OP doesn't want to run custom brakes (required with a custom hub), and there is an easy to source 8" wheel that should work fine for him and has the look he wants. The only issue is the rear, and there are easy solutions there as long as he is willing to let go of his stock housing.

Yeah the front really isn’t the issue. The rears are harder to find, especially in combination with the front because of the much lower offset needed.

One solution is actually a wider rear axle, if 18x9’s or 9.5’s are the goal then a 68-70 B body 8 3/4 will put you in a spot where +30’s should work.

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.

May not find the exact wheels you want, but it will give you more options.
