I thought really hard about that, the only thing is reading here, I get the impression that K20 and K30 hangers, crossmembers, etc. don't interchange.

Finding K30 stuff would be worse than finding a complete frame.

I can always wait until I get it home to do some direct measurements of the K20 to K30 differences.
