Do you already have the tap and handle? You might do just as well by getting a new rear DR, again. They usually aren't that expensive. Unless you have to have that exact DR.
No, but this is a good excuse to get one, haha. It doesn't *have* to be this specific one but I would prefer to use it. I have a Shimano Tourney I've been using on this bike that works just fine, but the bike has a new paint job and I polished all the old silver components, the black RD sticks out like a sore thumb.
What can I say, I'm a stickler for looks
