Jumping on this thread with a question. I replaced my pan and filter on my 63 Dart, and now want to replace the transmission cooler lines and eliminate the no longer needed inline external filter. The slant six engine is if from a 68-75 car but don't think that matters when discussing these lines. Which one of these sets do I need on Classic Industries? The first one seems to have the similar bends my original three piece set has, so leaning that one. Thanks!
