Richmond Gears?
If you have a 6spd car you would have a 3 series carrier thus needing a 3 series gear. If you have an auto with 2.73's then it would be the 2 series. The 2 series gear is thicker then a 3 series. You can run a 3 series gear in a 2 sereies carrier car but you would need one of the spacers to actually have the gear make contact.

...That would only be true if... It was an OE stock, non-modified or non-rebuilt differential. If those pre-reqs are not met... it could have anything in it.
The difference between the "series" of a peticular carrier is its flange height, relative to the bearing journel of the driven side. Typically, a specific "series" will fit and use a specific range of gear ratios due to the size of the pinion head. But... the gear manufacturers (for quite some time now) have been manufacturing gear sets with a flange height difference (or in other words offset) to utilize specific gear ratios to work on a different "series" carrier.
So... in short, a range specific ratio like that of a 3.73 can be used on a 2 series carrier by manufactureing the ring gear thicker to make up that distance. They are also known as "thick" gears... and there are also "thin" gears to go the opposite way in flange height and gear thickness.
