I have located a 1970 LeSabre non-posi differential with a 2.93 gear set. I would like to put the gear set in my 1970 GS455 posi differential that currently has a 2.56 gear set. Are the ring an pinion from the LeSabre the same as for the GS455? The GM parts book says that they are but I would like to have someone confirm that. Thanks.
