How much work to put this rear into a 67 GS 400? I'm an engine guy, trans-swap guy, front end and brakes. I'm not afraid to have some welding done to get this in and rolling to replace my peg-leg factory job, but wondering if it might not just be A LOT easier to just swap the rears between my '70 442 and the GS. The 442 has a Posi and about a 3.50 (never counted gear teeth, just eyeballed the pinion while turning the axle) gear set.
