Welcome to the forum, great site, great members! The rear end should not move at all. The case and frames holes are sized pretty close. The top bolt holes may be worn, as under acceleration the differential will try and rotate up in front. Check the bolt for signs of wear, and also check the frame mounting holes for any wear. If the frame holes are worn you have several approaches, weld hardened washers on the frame, or get a stepped bushing that fits the bolt (have to drill the frame to accept the bushing). I'm sure others will chime in and help.
