Slayer cable guide question

[bandit350]

Question about the 2011 Slayer cable guides on the downtube. Seems like they are made for 4mm cables. Somehow I smashed the top of my derailleur, resulting in the housing cap breaking off in the rear derailleur and shearing off a tiny piece of the der. up top. I'm replacing the shift cable and housing but only have 5mm as I buy in bulk.

Does anyone know where I can find the cable guides and who makes them? Ideally I'd like to buy a few and switch all out. The easy answer may be to buy some 4mm cables at my LBS. I borrowed the pic from NSMB but can take some up close shots in the morning if needed.

You could just bore them out to take 5mm cable jacket, and then order new ones in 4mm if you can find a source for the 4mm bulk cable
