73' B3 340 Duster pro touring build

My opinion (worth a whole $.02) is that a rear wing of any kind looks like azz unless its at least as wide as the deck lid at the point where it starts to curve down the rear of the car. I like the idea of the mini Pro-mod, but again the pic you show of one is too narrow, doesnt look right to me.
How much longer is your best guess before you get it home?

Sorry to pile on here butt... I have not seen a spoiler on the butt end of a Duster or Demon that looked to me like it belonged there. So there (worth about $.01).
They all look to me like... "Look! It's a race car now!" I like the clean factory butt end on these cars.
