73' B3 340 Duster pro touring build

Yea, the verdict is still out on the spoiler...been thinking about making a mini Pro-Mod Aluminum bolt on..but well see what happens when it's painted.

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?
