So... the new OH plate for my wife’s Model Y showed up in the mail today (in TX)... Just a single plate.
According to
https://www.10tv.com/article/news/lo...4-17e29a0acc2a , Ohio stopped issuing front plates as of July 1. Existing cars with a front plate no longer require the front plate to be mounted. And we moved out of Ohio 18 days later!
Now we just need to receive the title and we can go get the cars titied/registered in Texas...
