What size diff' casing am u likely to have on my car? It's a '88 325i with an lsd. Not sure on the ratio. I know there are 3 sizes of case but without access to all three for reference how do I tell which one I have?

How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

Should be the 'medium' size case (the largest for the E30), ratio either 3.64, 3.73 or 3.91 I believe.

Hi, if there are two ratios listed for a model, is one for a manual and one for an auto? If so which?
