Have you ever seen the hood of a 1988 thunderbird turbo coupe? http://members.***.net/turbocoupe50/88tc3z.jpg
The hood came like that stock and you coupld probably get the parts from a bone yard cheap. There's a duct with a seal that goes to the passenger side so that the intercooler gets air. If I wasn't planning to make my nostrils into ram air on my bird, I'd sell you my ducting but you'd still have to get the scoops. Can usually be had for cheap at the JY and they just drop right into a hole.
