License Plates question

[Ms Grumpy]

Many years ago I purchased a set of 1972 dealer plates for my Chevelle. I did not use them because I had a custom plate already on the car. Well I would now like to now register these plates to the car. Today I was at a swap meet and was looking at some 72 plates (always looking to see if I find ones with a unique number/letter combination), and talking to the guys who sell them and was told that it is difficult to register the dealer plates to a classic car. Now in 1972 Michigan started using the stickers in the corners of the plates, and they only produced truch plates for the first half of the year. I don't like the truck plates because they have an expiration date stamped on them, and that is why want to stick with the dealer plate.

Just wondering if anyone has recently tried to register an older dealer plate to their classic car, and if so has their been any problems?

Thanks for any help...
