Part Numbers - help!

I guess this applies to all Skoda's but as I've got a MK2, I put it in here ;-)

I'm on the search for a replacement dash after the accident.

Looking on Ebay, there's a few listed with very similar part numbers - apart from 4 or 5 digits at the end.

Example: mine is 1Z2857007A AE47H, Ebay is 1Z2857007A AN47H

Any ideas on the end numbers - I thought it was trim colour?
