I have asked BMC for some advise, but they pretty much said I need to go through Techco, I have called Techco, but it doesnt sound like they have actually took a Challenger apart, only chargers. I have also found out that the intercooler water pump bracket that came with the kit is wrong. Techco is going to try and get me the right one. I finally got a copy of the wiper mod that needs to be done and was not in the instructions.
