Will the subject gears fit into my 81 Grand Prix. They are both 10 bolt and they are both a 7.5 ring gear. Thanks.

as long as you use the carrier with them. The ring gear is much thicker on gears that are 3.25 and numerically higher, (also known as series 3 carrier) and will not fit with the 3.08 and lower carrier.
