Hey all... first post in the main forum. Picked up a '74 2002 in October and absolutely loving it. After getting a bunch of work done on it over a couple of days, we went to install a new ceramic coated IE street/track header, only to find during test fitting that the idler arm barely clears the bottom two tubes. With the center link back in place, the nut touches them. I've read that this happens occasionally, and that heating them and banging them out with a BFH is one method to clear the arm, but I'm afraid I will ruin the ceramic coating on my header. I wasn't able to get in touch with IE (I guess they are closed for the weekend). Any advice on how to proceed? I'm so disappointed that after all the work we did without any issues, we were stopped right as we were finishing up... we were so close!
