All,

Does anyone remember what the option code was for the 3.73 upgrade in the 07-08 GT's? I halfway remember it being paired with the spoiler delete, but the more I think about it, the more I think they were independent of each other.

I'm looking at a used GT here in LA that has the spoiler delete. I want to figure out if it has the taller rear end as well.

Thanks all...

the tag on the rear diff cover should tell you what ratio it has. if not, the door sticker on the drivers side should.

Ahh, totally forgot about the door tag. Thanks a bunch!

I can't see the spoiler delete being connected to the rear end option. I would use the pumpkin sticker since it will simply say the gear ratio. I can see mine without jacking up the car.

3.73 was a stand alone option, best way to tell is tag on rear diff or the axle code on the door plaque
