Odds of them bolting on are very weak. What they refer to is cutting down your sprockets and welding on Cat rims. A common technique for fixing older machines. Then you only have to make sure rollers are proper dimensions to work.

There ought to be some good used tracks around. I bought a pair this summer. H3, HD3, H4, HD4, and the 650 series all use the same tracks.

I'm the guy that gave you that info. It is from a Cat conversion book i have for converting to Cat undercarrige on non Cat machines. The Cat tracks work as a track group (with grousers) and the rim is a D3 sprocket rim It is a common practice to weld on sprocket rims. I have sold these before to work on HD4. Cat D3 are more common inexpensive and also one of the small chains you can buy as Lubed chains.
