flipping the rear subframe?

WinstonTJ is on his way to my house. We are going to attempt to flip his rear subframe in order to gain some rear camber. Is there a project blog that can guide us through the process or a link with pics? Can someone give us some feedback on what to expect and do? He likes to ask alot of questions so I am hoping he has a general game plan. Next weekend we'll do his five speed swap.

The procedure is to turn the rear subframe mounting bushings upside down by exchanging them left for right the mounting holes are offset to enable this.

The reason behind doing this raises the banana shaped rear subframe up into the car by about a half an inch or so. This is done to REMOVE EXCESSIVE CAMBER ON ANY LOWERED '02, it does not add camber! Too much camber is actually a bad thing, excessive tire wear, less tire contact patch while cornering..... "really?"...."yes, really!".

Many '02 racers in the past would even make up welded mounts in varying highths to adjust the rear geometry when rules stated they couldn't make the trailing arms adjustable.
