FA,
Having put the 1st top on my TR-6 years ago with less than perfect results, I'd say that it is a very difficult job if you have no previous experience. I consider myself to be pretty mechanicaly inclined, but the whole top installation thing got me baffled. Maybe someone else can provide you sage advice on doing it yourself! Most shops familiar with this type of work charge 3 or 4 hundred dollars, from what I've seen....
Mike: I took my frame and had it stripped and powder coated the correct black color. It cost me 125 dollars and it looks great! Make sure all of the pivot connections aren't loose, and the rivits that hold the header rail onto the frame are tight before you have it coated,
Good luck!
Mark
