well, my friend made one on the exact same sled. and he did an OK job, he didnt spen enough time shapping it, but it still works great and keeps his sled running COOL!
there are two ways to do this, one destroys the factory hood, you cut the stock hood up and uses it as a frame, most people dont wanna do it this way as it does destroy the factory hood
second way, my buddy took some 1/4" x 1/8" aluminum strap, and made a frame that went around the base of the hood at the belly pan, the shock tower areas are a little bit hard to follow the belly pan, but doable. then he took and bent peices to run up over the center. for the guages and headlights, he made a fiberglass housing, nothing special, but he still has lights and guages. and also keeps from burning up the ECU with it being a efi sled. the mesh he used is the same stuff most people use to make vents, its called pet proof screen door, you can find it at homedepot and lowes. mine was around $13 for a roll. and the roll will make an entire hood and have some left over. to attach it i think he just riveted the mesh to it somehow... i can call him and have him take some pictures and get em to me. the thing has been realy durable, as he rolls his sled quite a bit, and hits plenty off tree branches. only problem he had was he didnt put a brace over the area where the pipe and the can meet, so he melted a small chunk out, would have been easily fixed with a brace there.
it will work out good the more time you spent on it, he got lazy and sort of half a$$ed it, looks fine, but the finish is alright.. he did spend the time to make it hing up front and attached the limiting cable so he can just hang it open. and on the back, he just took the straps off the factory hood and riveted them to the mesh one, so he hasnt had a problem with it coming open.
one though i just had and descided to add, if you had acces to a tig welder, or even if you dont, i thing the ideal metal to make the bottom outer layer would be 1/4" aluminum rod. not flat stuff, that way you could bend it around the shock tower hump and it would end up fit better, just seemed like it would make it fit better for overall fit and finish... get some pics when its done!!
