Clutch Master Cylinder Question

[Jruby38]

Are all Clutch master cylinders the same for all models, or is the Interstate different?

Thanks

Standard and Tourer have a different part number than the Interstate.  All the associated parts (piston set, switch, cover, etc.) appear to be the same part numbers, and the main casting appears to be the same.  Not having each side-by-side in front of me, I can't be sure, but the only difference I can see looking at photos is the clamp for mounting to the handlebars, with the IS version having accommodations for mounting the switch box for the radio, etc.  So, from what I can tell, the master cylinders themselves, without the clamp, are interchangeable.
