I believe the 7.625 carriers and gears also fit but will require different axles because the 7.625 carriers have a different spline count for the axles. But if your going with a 7.5 carrier/gear set just make sure it uses the same spline count as your axles. Also make sure the carrier is the correct series for the gear set your getting. I believe 3.73 gears require a 3 series posi carrier. But if for some reason you can't get a 3 series carrier they sell spacer kits for the gears.

I have to ask...how long does to take you to put gas in that car?
