I picked up a fairly clean 04 660 Rhino today that had a rod bust the cases. I have a small salvage yard and have 2 complete 660 Grizzly motors that at least have good cases. I've read a little about what needs to be done and doesn't seem to be a big deal. I noticed that the transmission gears were said to be different and so I checked a schematic to see how much. The 02-03 Grizzly have different transmissions than the 04+ Grizzly. I know one of the bikes I have is an 02 and I'll have to check on the other. I'm hoping its 04+ so that I would have whichever I feel is the best. Here is the schematic for the transmission on the 02 grizzly and 04 Rhino.

I don't have a problem opening up one of the bottom ends I have and putting whatever gears need to be put in from the Rhino, but I was wondering if it would be possible to interchange gears from both bikes? I would want the lowest for low range and highest for high, best of both worlds I guess. Has anyone any eperience with anything like this and from looking at the schematic what would be my best gear set combination?
