suspension question
 

I have an 85 gs and want to do a suspension swap. I know a guy that is parting out an 84 se. I heard that a lot if it(struts, tie rods...) are the same on all s3's. What exactly do I need off the se? I know I need the rear end and all the brakes. Im sure this has been covered before but I searched and couldnt seem to find it. Thanks for your time

Rear end, calipers, axles, Emergency brake lines, front struts/hubs, brake proportioning valve, master cylinder.

Most people do not get the last 2, but it would be better if you have the PV from a disc brake car as not to throw off the brake balance.
