I have been having trouble hitting the mode start hole on my GnR. After having a look I was pretty sure I was missing something and with some help from a Pinsider who provided a picture for me I have discovered that it is this metal guide:

So I am guessing that I won't be able to find this part for sale anywhere as I assume it's a game specific part and unlikely been reproduced. (Please correct me if I am wrong.) My question is does anybody here have the skills to make something like this for me? I realise that may be a little tricky as I do not have the part for somebody to copy!
Any ideas chaps?
Thanks.
