i know this is an old thread but i have an r32 gt-r diff, axles, hubs etc in an r33 gts-t cradle, all transfered easy peasy
unbolt the tail shaft yoke and swap over, and use r33 upper control arms to clear the struts
i will fit the gt-r cradle soon for more track but i'm still painting it and welding washers in the bushes...hehe dodgy
