Where to find adjustable rear sight for Single Six?

[sactime]

I have a ruger single six and I am looking to replace the fixed rear sight with an adjustable one.

The only thing I could find is this: http://www.midwayusa.com/viewproduct...tnumber=421942

It does not look like it would fit. Can anyone help me out?

Here is my gun:

So I am out of luck?

sactime if thats a 3 screw unconverted I'd leave it alone unless it's in bad shape (cosmetically). Depending on the MFG. year these guns are some what to highly collectable. If you want a adjustable sight you can always look around and pick one up at a fair price. Redhemi
