Correct I just swapped 3.42 posi guts from a 68gs into my 70 Estate wagon. The bearings are actually different and had a hard time finding new ones for the wagon. We ended up leaving my axle bearings in place. The 68riv uses sealed bearings.. Btw I now have 68 gs axles, a 9-3/8 open carrier and 2.73 gears if anyone is interested
