In the UK you can buy OEM R/H only:

(That is the 8 speed that will work fine on 7).

Here is the tech.doc:

The part number is ST-EF60-7 - ask your LBS to order the part in for you, off the top of his/her head the sales staff may not know this can be ordered, but it almost certainly can, and definitely can in the UK.
