The old "cart before the horse" eh?
I'm not sure anybody here would have any updated information on this issue more than AMP does. Did you ask AMP your question regarding the model year issue?
I don't trust anyone doing service on my vehicle other than me. I've seen/heard too many stories about some jackass (dealership or otherwise) messing around with someone's vehicle and causing an issue.
I'm also old, ornery and I hate everyone. :LOL:
