and his email is berniebilski@cox.net. I have no information on the lines. Here is what Z1 says about AC differences: "The Radiator and AC Condenser are MUCH different. They are much narrower on a TT so the intercooler piping can go around each side. The front lower core support is also different (but can be modified to work with a little cutting and welding) because the TT radiator and condensermount farther down into brackets, because they are taller to make up for the difference in width. There are some differences in the AC lines also. The upper radiator hose on the TT is different but the lower one is the same."
