Possibly, series 2, 3, 4 gear carriers?

The gear carriers are different depths to accomidate the different thicknesses of crown gears.

Higher (numerically) gear ratios generally have a smaller-diameter pinion gear. The carriers that are compatible with higher-ratio gears will have the ring gear flange farther to the right, closer to the centerline of the pinion gear. That way they don't have to use a thicker ring gear.

Different rear end designs will have different break-points for their respective carrier series's. In other words, one might use one series for 2.73 & up ratios, while another will use one series for 3.08 & above, but a different series for 2.73 and below.

Some ring & pinion gears are also machined to fit a carrier series that they would have NOT normally been originally been able to be intsalled on.

If you have a series 2 carrier normally meant to carry a gear set of less than 3.08, a set of these 3.73 or 4.10 gears machined to physically fit a series 2 carrier WILL fit, but a standard set found in a donor car in the local junkyard would not as those are machined to only fit a series 3 carrier.
