Will a 325i LSD fit My Euro 323i?

[JamesE30]

I'm about to buy an LSD for my e30, and I've decided on a 3.73:1 Ratio.

It was removed from a 1989 325i.

Will it bolt straight into my 1985 323i?

Thanks in advance!

You will have to loosen the nut on the rear half of the drive shaft to shorten it slightly, but otherwise will bolt straight in. And you will probably need to use the speed sensor out of the 323i diff, will depend on the plug connection you have/get.
