iirc theyre offset on both axles... they might be good swap in a sammi or something, but better be sure to get wheels cuz htey have odd pattern... i dunno that theyre desireable though
I'm a Sammi guy, and I've seen this come up a time or two. Seems the general consensus among those who've tried it is they're as weak as Sammi axles. Pretty much a waste of time to swap them into anything.
ring and pinions for them are specially made @ about $550 a set, so don't break them but they might be worth the parts, what ratio are they. ill take the gears.
for free or real cheap they'd be worth getting and parting them out for spares to rover guys. they're not really good candidates for any kind of swap though.
