I agree, there are definately going to be other cars that will be able to use the same carrier... unfortunately, I doubt the exhaustive research is going to get us any better deal. If you look at their price chart (WavetracŪ Differential - Application List), we are already about -$200 for similar apps. If we were still struggling to get enough people to have this made, then it would be worth my time.

For a cross ref example check out this nice chart: http://www.w124performance.com/docs/...ferentials.pdf

It takes a LOT of research to get all the apps for a part... My thought, this rests with the dealer that will be making all the money.
