was told an explorer with disc rear would work as a swap. dont hold me to it though, just hearsay. also, for the front they have a thread on toyotaminis.com about it. 4x4 front calipers, wilwood rotors and hats, makes it a 2 piston setup i believe, rather than a 1, and ups the front disc diameter to just over 12 inches.
