2.45 were in the 8 1/4. I took the complete rear end out of a gold duster, way back in 1998, put it into my Duster360 that year and drove to Carlisle. Cruising at 70mph with 235/60/14 tires, 2.45 gears, the 360 was ticking over at 2650(ish) RPM. 22 mpg all day long, and the 360 torque, could always roast the right tire ! Have left that rear end in my Duster360 ever since ! . . . lowest numerical gear I have heard of for 8 3/4 is the 2.76 gear set. . . . good luck with your search . . .
