Will do. The TFFN web site gave a lot of information on fitting the Dougs TRI -Y headers into the Falcons. I got them off of ebay from Summit. There are rave reviews on how well they fit with zero mods required. The ones I have ordered are part number D660YA and are for the 1963-70 260/289/302 with a C4 transmission. There are a couple of responses in TFFN where folks installing that particular set have to make some mods or at least have trouble where the shift cable bracket is for a standard transmission.
Thanks for the kind words on my car. I am about finished polishing the paint on the roof and rear half of the car. I will send pics soon. Then I will roll the car out of the garage, turn it around and put it in face first to finish the front half. Doesn't make much sense I imagine but it keeps me close to my electric heaters!
