Found it at an upholstery shop for about .29 per foot. The opening on the car in the picture now has a mesh grill behind it to keep out the opossums. It is silver at the moment, but the wife keeps asking me to paint it black. This car is now her Friday car. DLee Attached image(s)

I like Rusty's idea about scoring the chrome on the line first, for sure if it's been restored before... rechroming is sometimes thicker, and not as sticky as the factory stuff. M

So that's enough air for a V8 in texas? Seems like most people cut huge holes, I was wondering if less would work. I'm going to try for leaving the bumper intact but have a valence hole that is as wide as the front of the hood. If it doesn't work I'll go bigger.

It is a stock bumper, I think fiberglass?? but the owner added an exra grille on either side of the existing ones. SO you have four non fog lite grilles in the front bumper. Sorry no pics available at this time. CCLINCOOLINGHOLE

I need to call Scott and ask him about the ducting for the hot air....i currently have a big @ss hole in the front trunk for the dealer installed A/C, I have a new (used) trunk floor to use if it would be worth the effort to do so....

Mike,I am at that stage right now. I need to cut the hole in the front for cooling air.
Was thinking about cutting below the hood latch but after looking at the pics above,I may need to re-think my plan. Here is the hole I cut last weekend for the hot air exhaust..................

These tech tips are of particular interest (Admin, I assume it's ok to quote for their site?): "Most importantly, keep in mind to increase in volume from the inlet or grill opening to the core face." "A common misconception among inexperienced racing mechanics is to “scoop” air into the radiator, cooler, or inlet duct. A scoop that tries to “grab” as much air as possible and funnel it into a restrictive duct will create a damming of the air, directing it around the duct, thus defeating the purpose. Air, like water, will follow the path of least resistance." http://www.crracing.com/apparel/shirts.html Andy

I found a pic.. anyone care to crop it down to just the nose of the car and lighten it? (I don't have that capability on my work computer, if nobody else does it I'll do it when I get home)

Just a link because it's a big pic

There is also a lower opening that you cannot see. I tried to run with just the A/C opening and I ended up cutting out the wheelwells. Mark Attached image(s)

I,ve provided a pic of my other V8 car with rubber bumpers and an ultimate air dam. The cutout is hard to notice unless you get down low to look for it. The key is to get the hot air out. Many folks try to vent through the floor or are nervous about cutting out the inner wheel wells. The best results are obtained by prviding a good sized cutout of the wheel wells for exhausting the air. David Lee Attached image(s)
