Ok now another two questions:
1. I don't see why it would be - but since the geometry is apparently different, would it be unsafe in any way to use the k4 triples on the k8 frame? Can I still use my k8 wheel?
2. I could just fill those spaces w/ weld on the k8 top triple before cutting and it should have a decent finish ya? - I would have to fill the [smaller] holes on the k4 top triple too...
Ok I guess that's three questions
Thanks again!
