I believe there were F- and A/G-cars ('78(?)-up) w/that ratio. Astro vans, too.

The 7.5" diff could be had with:

2.14 (79 Malibu), 2.29, 2.41, 2.56, 2.73, 2.93, 3.08, 3.23, 3.42, 3.73.

Edit- And the 4.10 as noted by BGH, below.

Don't forget the 4.10. Many of the older 4X4 S trucks had 4.10 gears.

My 1991 S-10 2WD EL has 4.10 gears from the factory, my dad's 1985 S-10 4X4 had 4.10's with the 2.8 V6.
