Need some basic help...brake booster

[1990m3]

How do I disassemble the E21 brake booster so I can remove the rod and modify it to the proper length? I don't want to break anything so I thought I'd ask before I wreck it.

I know it's a kind of retarded question, but thanks anyway

I wouldn't attempt to remove the rod. Just modify it with it on the booster. Are you rethreading it? I just had my buddy cut the rod off the e30 booster and weld it to the e21 rod, after measuring of course. Works great.
