[70ina30]

I went to change out my rear seal on The transmission of my rb25 today. It wss very leaky and wouldnt hold anything.
So i removed, drove to autozone and looked up a z32 one and purchased.
Got home and no go.... the 300zx one from autozone was too small.
So now im trying to find one online, however i am fearful to end up with another small one as they all advertise that the rb25 also fits the z32 vg30.....
Can someone please help clarify

Thanks
