options for 3.08 gears?

[cell]

So, if I want 3.08 gears to put in my rear end, what are my options? Does anyone make aftermarket gears, or am I stuck finding something used which hopefully isn't too worn?

You can buy Richmond gears from Summit Racing or Jegs. It's pretty hard to beat their prices these days...

wow, that is cheap. now I just need to figure out if I have a series 3 or series 4 carrier.

but I don't really need to worry about this for about another month or two. getting the engine back in the truck would be slightly more important

hmm, that makes me think. Should I get a 3.08 gear set and a newer 5 speed manual with overdrive, or should I try and get a 2.56 gear set and keep my original SM465 4 speed with top gear at 1:1?

hmm...

I'd go with the 2.56. There isn't a 5 speed with overdrive that i know of that is strong enough to hold up bolted to a strong engine and last very long. (very long defined as 100k)

i just went through this, and ended up getting a whole rearend w/3.08's

I have been having similar issues, I am installing a 5 speed with a nice 0.64 overdrive so you can still run low gears. the tranny i am using is a tremec TKO 600 rated for 600 lbs of torque i hear nothing but good things about it, but i also have a similar problem about the rear end...

how do I know what posi carrier i have? I have a used posi unit but I don't know if it is for a 3.42 and up ring gear or a 3.42 and down ring gear??
