That's cool, i've been told a few times that it was possible to use those disc brakes off of a Gr. cherokee but i've never come across anyone whos actually done it so never gave it much thought. That's cool to see that it works without too major modification. Could you tell me why the rallyes didn't work? I'd be interested to know because i'd love to do a swap like this but would probably be stuck with a stock set of wheels (such as rallyes) untill money allows an upgrade.
