re-using old license plates
Texas, the plates need to be a matching set YOM and in like new condition. If they are restored, and repainted, they need to be repainted the exact color scheme that they were for that year. Texas changed colors every year back then. For example the 68 tags were black with white lettering. 67 was white with black lettering.
You take your restored plates to the DMV, they inspect them to see they are in useable condition, and charge you a $60 one time fee. No little registration stickers on our tags.
