We should trade! I have a set of THY-324Y-C headers that fit inside the frame rails fine, but basically were rubbing on the firewall on the driver's side. If you have clearance in that area, these might work for you. Too bad we weren't closer, or I'd let you try to fit them. I could have just hammered a dent in the firewall, but I didn't want to do that. Almost bought the 323y's as I've seen others fit them just fine.
