I called our local UHaul
dealership in Forest Park, IL and spoke to a nice lady who must think I'm a nut. She thought I was asking about getting a 21 year-old part when I asked about ordering a new rim for our 1986 16' UHaul
. Finally, after talking 3-way with her boss, we figured out they could order part # 23516006 and get the right rim for me. Their parts repair cost for the rim is about $24 and they're going to charge me a few bucks more. I ordered two rims, so they should cost about $60-$70. They'll be in to the store in a couple days. Very easy!
