My car didn't come with one. Anyone know where I could get one? eBay turned up nothing for that model (got older and newer, but no 6Ns). Should I just keep checking and hoping?

get yourself to the scrap yard. pretty sure they will let you have one for nothing. I might be able to get to my local on saturday and see if they have one knocking about.

I need to go to some scrap yards for other bits, never thought for manual though.

If you can that'd be great!! I'd pay.
