Why don't you keep your current setup on until the axles get here? I looked adaptors when I got my first set of wheels and I could only find options that were 2 pieces and spacers from reputable sources were expensive
I already found a home for my existing wheels and Dynatrac is 8-12 weeks out on their standard packages. I was hoping to find someone with some used 2-piece adapters to save some money in the short term.
