If you know someone with a 2018-2019 Nissan Frontier I've got one for that as well.  Part number is  (90046).  

If you have the tech package w/adaptive cruise  - you'll have to try a few settings to get it to work correctly if you have Adaptive Cruise control.   I found just changing the tire size in the software by 0 .1 allows it work just fine.
