Inferno Red 74 Duster!

That old trailer hitch is kind of neat and I even remember bolting one in through the spare tire well when I was young.

Ad far as gears go I had 3:90 gears in one of my old Dusters and dam did it rev on the highway, so if you are not into to much highway driving 4:10 gears will work for ya. I think I ran a 265 50 14 back then so it might of helped a bit if I had a taller tire, but dam does it make a difference in off line acceleration going from my old 3:23 to 3:90's.
