1967 Dodge Dart GT 273 4bbl. factory buckets and console, rottiserie restoration.

A bit tough to read. What is under the first line a+b? How about the second line X7Y? and the PNT is it DE2?
Hi
I will take a better pic of tag when I am back to the garage I have it stored in, this will take a day or two as it my quonset is a 2 hour drive from here. Thanks for your interest, if there is anything else you would like a pic. of let me know. I will try and get some of the underside for you as well.
