I know what car your talking about and thats risky. I have never looked real hard at a 2g rear to see if they have a lsd tag like 1g`s but i believe there was a tag in the drivers door also. I am pretty sure all 2g rears are the same i have never heard of any differences.
becarefull when buying a car that doesnt run there are so many things that could be wrong with it.
