LBP upgrade for 18" wheel conversion

Here is a screen shot of the exact wheels/part numbers. I did use a small space and will try and find what I used as well. There is actually a 10" wide wheel that could be an option too but it may get tight. Hope this helps!

Yes, any help is greatly appreciated? My 8.75 is getting the BBP axles along with new gearing and a PowerLok unit. Next up is wheels, and the struggle has been real trying to find a set i like. I really want to make this style like you have work with my setup if anyway possible.
Thanks again.
