Downtube cable stops for modern groupset

I need some downtube cable stops to work with a modern Shimano groupset on an older frame.
Something like this:

Can anybody explain to me what I need in order to make this happen? Is there a specific Shimano component I can buy?

Cheers, Horatio

Ask your LBS or search for downtube cable stop/adjuster. ~$15 I think. Shimano units are nicer than Campy IMO.

Bought some Shimano ones from Brunswick St Cycles- $18.00.
Thanks.
