Urgent: Control Arm Bushings!

My control arm bushings need to be replaced (again), however that's not really the issue. What I'm wondering though, is if the E46 M3 LCA Bushings mate to the regular E46 control arms. i.e. can I use the M3 bushings in either carrier? I remember seeing a post about this sort of thing, but I couldn't find it. I have a track event next weekend, so I have to scrounge up parts and get this taken care of ASAP.

M3 control arms, front/rear suspension, etc is completely different than any main stream E46.

In order to save cost, I would trace the LOemforder dealer around my area, and get these OEM control arms for 3/4 of the main dealer price, and then have them installed by a professional BMW independent place.

These are the OEM manufacturers of the control arms, and the bushings.

Their prices are 3/4 of the main delaer price(I wonder why is that)

The bushings include the housing and the screw also. Main (s)dealer just supplies the bush.

Here is the index of the bushings by manufacturer:

Since I can't send you a PM, do you know how the mtech-II control arms differ from the regular ones? I've heard that they have a heavier duty outer ball joint, but is the geometry different at all? If the ZHP package gives additional camber, something must be different.
