Re: Oregonmon's white 1990
If you use washers, your rack bushing won't have anything to rest on. If you rack bushings don't have anything to rest on, it'll jiggle around. Don't have a jiggly rack, make a full sized spacer.
I'm guessing HD has a wide enough 1/4" aluminum bar stock we could use. I could just cut it to length, and drill two holes to match the subframe mounting holes. Let me know.
