This is a really old thread, but proof that I use the search function before asking questions 
I'm really surprised that there isn't an updated option available for the C3 by now. If one exists that I am missing someone please point me in the right direction.

The good news is that the C4 Bearings are cheap and somewhat easy to replace. Most any Auto Parts store can get a replacement.
The bad news is that its a completely different design and there isn't any way somebody is going to adapt it to a C3.
The good news is that a C3 Bearing properly set up will just about last forever even doing Motorsports.
The bad news is a C4 doing motorsports gets its bearings replaced every year as just a part of normal maintenance.

The driver's rear tire is leaning in quite a bit at the top. I realize there is a camber adjustment, but I wonder how could one side be so far out? My buddy has a '78, he said his was leaned in like that and had to replace the rear bearing. How can I check for sure?

The shear cost of R & D...and getting the parking brake and the strut rod attached to you can still adjust the camber would be a ROYAL PAIN.
The you have to worry about some company coming in from overseas and stealing your idea and selling it a lot cheaper and thus making it so you could never get your money back from your investment in this.
There is A LOT going on back there to make this work and be RIGHT and not a CLUSTER!

O.K., looks like that is still in the $100 range. Of course, "while I have it apart" will cost me more $$$...

AND...if when you are at the rear of the car...and you look at the concentric bolts that hold and adjust your strut rod at eh differential on the LEFT side. If the head of the bolt is at the 3 o'clock position...and your rear wheel is leaning in. There is a very high probability that your side yoke is worn down...which is easy to check.
On the RIGHT side...if the head of the bolt is at the 9 o'clock position...it is also more than likely shot.
