I thought Marti also sold the "correct" rivets for the door plate.?? If correct doesn't matter a normal rivet should work.
Fyi. In CA, they didn't really pay Attention to a vin on the door since that can be replaced. Mine door doesn't even match my apron vin.
Here's what my brain says: I have 6.75" backspace on 18x9.5 in back. I clear the lip and am about 1/2" or so from the leaf spring. Your 18x10 would make up the difference between my 6.75 and your 6.37. But your 1/2" narrower so it will still be close.
Sooooo maybe a 1/2 -3/4" spacer?
I realize that. I'm saying If You have an old registration from Arizona with the sellers name on it, the " chain of custody" proof that dmv might ask for becomes easier.
The title bond is easy to get also so dont stress out on that.
It's super convenient. Cost is $40-100 depending on how close they are to you. Go on DMV website or look on Craigslist for a Mobile Vin Verifier. It all was pretty painless. Do you at least have an old registration? You can use that also.
