Pete, The manual shows 2 different coils from the donor. The 1600cc Pinto had a .531 wire diameter. The Mustang had a .565. The book says to cut a coil and a half from the .565 coil. This does work but the ride is very stiff. With your wire diameter of .515 I would start with a 1/2 coil. The Pinto spring with the .531 diameter sets the height pretty well. You can get 2 fingers in between the tire and wheel lip with a 245x60 tire on the front. I think 1 1/2 coils would drop you so far your pan would scrape. If you want to go with the tubular lower arm and the coilover maybe we can work something out on the friendly payment plan! Then all the trial and error will go away.
