Answer
Hi Kevin:
Those letters are only used during the manufacturing process and do not correspond to anything usable in our world.

For used parts...Try this site.  You may be able to find what you need.

www.car-part.com
It's the website all the salvage yards use when they say "Hang on--let me see if my other yard has it".  Actually it's an online database of all the salvage yards in America.  You can search by part, location or price

Happy Holidays
