Has anyone ever installed an r32 gtr diff in an s13 subframe ? I heard it's like the q45 so you'd use a q45 and a z32 tt axle with gtr/z32tt/q45 hubs. Swap the rear cover from GTR to S13 But what about the input shaft ? can I just swap an s13 one in and bolt up my driveshaft ? gtr input shaft for reference
