I've got a Limited Late Model with a plastic nose,What I need to know what is the best way to build a air box in front of the radiator,in a confined area,I know it will more than likely run a lot cooler with the air going stright into the front of the radiator!Would it best be made of thin sheet metal or plastic,like we use for skirting around the bottom edges of the sides and nose?If you can, kind of draw it up for me too.Right now I don't have the measurements,but I'll get them this week end and put them on this site.Thanks,nun20er or choochoo.
