The posi carrier has springs. the open carrier does not.

And yes posting a picture of the differential with the cover removed will helping us to verify the axle if you still are not sure after reading Cory's statement above.

your spid/rpo will have a the code G80 if you have a posi

This is a positraction carrier.

Found the SPID code sticker, and yes, it does! Woot! Is that rare?

this is one of my MUST have options when buying a rear wheel drive chev or gm car or truck k3:

so you wont be doing any peg leg burn outs then

Yeah, no. I think 'peg leg burnouts' are kinda sad... But it does cost half as much in tires!

The was standard with the towing package sedans from 94-96. Towing It wasn't common, or rare to be on the 2.56 RM sedans. It was sort of in between. But it did seem a bit rare on the 91-93 Roadmasters. Wagons seem to follow their own rules, and were a bit more rare. No 2.56 posi wagons.

What does this "2.56" mean?

 

[463]

that is the gear ratio. so 2.56 rotations of your drive shaft to 1 turn of the axel. the rpo code i think is gm8 or gw2,gw3,g11,gt1. the lower the ratio the higher the speed the rearend is so if it was 4.10 gear would be low speed fast (drag car or truck the would pull 10000 + lbs)

I think my SPID code pointed to a 3.08... So what's that mean? More power... Or more speed?

More of a balance between power and speed. IMO it is a better ratio than the 2.56.

3.08 and 3.43 IMO are the best ratios unless as someone pointed out above that you are building a drag/racing car. Some here even like the 3.73 axle for good fast takeoffs.

Cool. This car just looks better and better... hardware wise. Electronically, however, it still needs fixin' (lumbar controls not working, passenger sear won't recline, trunk won't pull itself shut, etc) but I like what I'm seeing and I thank you guys for the info!
