Hey everyone,

As I hunt for a 94-96 wagon I've been looking at alot of variations of what could potentially be a tow package car, posi-traction car, etc. (owner usually doesn't know). I've been reading threads on the tow-package and posi and have a question:

Not all LT1's with mechanical fans have the tow package and not all tow package wagons have posi, but are all cars with mechanical fans also cars with posi traction? I'm trying to make judgement based on pictures in ads... or is there really no way of knowing without jacking the car up and spinning the wheels?

I know I can look at the tailgate code, but so far when I've looked and peeked at the code for posi-traction, but I couldn't locate the ID number. Maybe I'm just blind or stupid (probably both LoL).

Thanks,

Casey

G80 is the rpo code for anti-spin rear differential. If you don't have access to the tailgate jam, you can always look for the tell-tale additive tag secured to the diff cover.

Trailer Pak cars did not come with the 2:56 long gear. Posi was not offered on the 2:56 gear, so if it is a towing car it "might" have posi, but it was not a required option.

The G80 on the SPID sticker is the best assurance without jacking up both rear wheels.

You could have the seller email you a picture of the SPID. All the info you need is on it.
