CT Year of manufacture plate display... failed. Anyone succeed?

[r-mm]

I filled out CT's B-320 application to display year of manufacture plates for my 1991 964.

I brought a pair of 1991 CT plates.

The clerk at the usually polite Old Saybrook DMV told me "these are not year of manufacture plates" and wend on to suggest the plates themselves were supposed to be manufactured by the vehicle's manufacturer. I frankly have no idea if this happened at some point in the distant past but the form clearly suggests all you need is plates from the year the car was manufactured.

Has anyone succeeded in getting this permission in CT?

I will say that they used to have a form you mailed in for this permission and I mailed it in to display 1973 plates on my Alfa. Which I did. I once got pulled over by a cop who had no idea such permission existed. I showed him the "real plates" in the car which he advised me to use in lieu of the YOM if I didn't want to meet a lot more cops. It did make me wonder how automated plate readers like EZ pass would react to this and whether I'm just courting disaster here.

That said - I do see a number of folks driving on old blue plates.

Anyone have experience to share?

In NYS you can use year of manufacture plates and they would be the "real" plates registered to your car. Not sure why you would have "real" plates and then put the YOM plates on, the YOM should be the plate registered to the vehicle.

It is quite opaque in CT. To the best of my understanding, they allow you to "Display" the YOM plates but it remains registered to the "Classic" plates which you must keep in the car. Frankly it sounds like a weird and poorly thought out system that maybe works for a parade not a daily but I want to hear from CT folks with experience please.
