I kinda think its one-size-fits-all, although I vaguely recall reading that a smaller bore size means a softer pedal. Make sense?
I didn't really know for sure, but I took a chance on the Centric model and it appears to be a direct replacement. The casting is pretty much identical, the reservoir is totally identical, and the identical bore size is cast right into the side of the unit.
We tested it out on a long weekend - 1500 mile trip up into New Hampshire and back to see the fall Foliage around Mount Washington... worked great. The pedal actually seemed a little easier to press, but I think it was due to having bled all the old fluid out of the lines. That stuff was nasty and dark colored... I suspect it had been in there for 22 years.
I also have heard that a smaller cylinder will make a softer pedal - but will use more travel. Yes... makes sense.
