GM 3.42 Gears, Low Mileage

I have a set of GM 3.42 gears that I bought a few years ago out of a low mileage (around 20k miles if memory serves me correct) 6 speed Camaro. I never ended up installing them in my car. The gears are in great condition and look almost new. I'm asking $50+ shipping to the lower 48.

These are a great cost effective upgrade for an automatic car. These are a smart option rather than spending hundreds of dollars on a set of aftermarket gears that will more than likely whine when installed.

Thanks for looking
