anyone done this. I know that the nwer 3.8 had them but not mine. Can i add an afermarket Flex-a-lite kit? if so which part number. should it have the A/C accessory kit as well as the temp kit? I have seen some where they put a capilary tube through the fins of the radiator for the temp reading up near the inlet. any info on install or anything else about it would be great.
