1981 Chevy Monte Carlo Rearend

I have a chevy 81 monte carlo with a stock rearend, 241 rearend gears (41 ring and 17 pinion) 10 bolt cover and 10 bolt ring with a diameter of 7.5 inches. I need to change to a 410 rearend gear can I just put in a 10 pinion gear to get this or will the teeth not line up right. If you order a 410 gear you get a 41 ring gear and 10 pinion gear. Is there really a difference. Thanks for all the advice. Gary

You will need to get the matching set. Also, going from the 2.41 to a 4.10, you will probably need to change the carrier too.

YUP, You'll need the 3 series ring gear carrier, and BOTH gears need changed as a set.

You might be able to find the gears and carrier in an S-10 for real cheap, and it will be a direct bolt in, but the spider gears will most likely have a different tooth count (you currently have 26 and the newer ones have 28) the spider gear sets will directly interchange in the carrier, unless you want to find a set of 28 spline axleshafts too.

you have to used matched ring and pinions, they are made at the factory to be used together and can't be interchanged, they even have the numbers stamped onto them indicating them as a matched pair

I have the same rear in my 81. I used a thick set to go to 3:73 Richmond gear sells them. Not sure but I think they have a 4:10 thick set for that rear.
