Cheers for looking Dave, are there any that you know have definitely come for a non a/c unit? It might still be what i'm looking for.
Another member had that exact part number and sent me some pics but it was completely different to mine.
I think the garage may have given me the wrong part number. I'm going to double check it with the MB dealer as I think they may have give me the part number for the a/c model instead.
Let me know if you have any and what the part numbers are if possible and i'll have a word with the dealer to see if they would fit.
