I think that '86 you posted looks good.
My brother in law had a red 1990 Saleen vert. My Ex and I had a 1990 Saleen clone too. It was done right and was stolen before it was complete.
I have one picture of it. My Capri used to be a Saleen clone. LOL If you look on the back of the Dugan Racing catalog (at least on mine but it's old) there is a red 4 eye with the 87-93 saleen valence on it, looks pretty good.
The bumpers are not shaped the same. They are close enough to makeit work tho.
Just use the GT valance and add Marshall fog lamps... GOD I MISS MY 86

Have someone photshop it for you
No chop needed. http://www.fquick.com/garages/Ford/Mustang/1986/7220 The car is a genuine Saleen but has had the air dam replaced with a later one. Personally I like the '85-'86 one better, but that doesn't look bad either.
lol that neon almost looks factory with that eclipse bumper...its like a first generation SRT4 haha

Wait...i'd have to say the GLHS is still way cooler...
