Or are you using Jimmy as a nickname for a GMC pickup?
4.56:1 is unusually low for a rearend on a light 1st gen suv. Most are 3.73:1 or even 3.07:1 in a half ton.
If you're talking about a 3/4 ton GMC, never mind. But 4.56:1 on a half ton Blazer is real low. And you'd do better with higher gears, like 3.73.

No, it's actually a Jimmy. It's GMC's version of the Chevy Blazer.
I placed the 410 gears in it when I restored the vehicle last year.
I'm running 33's on them, and I did install a gear vendor overdrive unit.
