Aluminum swing-arm questions

I'm looking for a swingarm and calipers.

I was given a frontend and both wheels from an early Suzuki ? something ? ( ? GS,GSX, GSXR, Katana ? ) but no swingarm or calipers...

Would like you opinions on which swingarm would be best/easiest modified... Who has mounted a sportbike swingarm, what did you use?

Probably easiest to modify a Norton swingarm, or build a custom swingarm.

Otherwise, get a good ruler, and go down to several bike shops and start measuring...

Old brits has a clearance on old swingarms, the non reinforced ones for $20.00. Hard to beat that.
