I think I have found the holy grail, the part I now have on order from my dealer I found on ebay.com, the seller will not send to the UK but my wee guy said he will get it for around £28, he also said that Dodge UK had ordered this part before.
Check this link, pictures and part number. Can't wait to get it and stop burning CDs
