Jack21,
Thanks for the local lead - I have their number and will call them tomorrow.
cobrashock,
Thanks for the confirmation of my objectives with this - heat generation and slip I don't need! You have articulated my aims quite well. My cruise speed on the highway will be well below 2500 with the 2.88 axle. I'll keep those parameters in mind when I make my call tomorrow.
I already have a "built" C6 and the Saturday Nite Special ready to install, so we'll see if they convert (
) me to something else!
Tom
