I'll give you the cliff notes edition. If you want more detailed instructions, I can write something up. No big deal.
I purchased the aluminum hood scoop from finish line. Here's how I removed the origonal hood scoop. I filled the scoop with foam, sanded the underside to the contour of the hood, glassed over the entire underside with 2 to 3 bid, turned the hood over, cut the scoop off, filled the area where the scoop used to be with micro balloons and epoxy, sanded that to the outside contour of the hood, glassed 3 or 3 bid over the top of the hood, placed the scoop where I wanted it, drilled the holes with a #30 drill into the hood and scribed a line from the outside of the scoop. Remove the scoop, measured in toward the center of the hood the width of the flange of the scoop, then cut the hole along that line.
Tristates hood, it comes solid and they sell a seperate scoop (or the Finishline one)
It seems pricey, but comes with a cool original style hinge. Combined it's essentially the same $$s as the stock FFR hood and optional hinge.
I've wondered if one couldn't take some laminated glass stock and cut it to look like the hood scoop flange. It could be bonded to the hood around the original scoop and some material feathered in where it meets the scoop to look like it was a seperate piece.
The ACE/AC hood has a pronounced bulge that is in the scoop area, so a flat insert will not fit unless you want to feather that area from 0-1/4" in fillers.
Besides these REPLICA "R" hood shells are cheap w/o the scoop, just cut the 9"x14" hole and throw on the $39.00 scoop per instructions. NO BIGGIE.
