1970-72 duster 340 scoop placement (two scoops)

Does any one here have an old shop manual or body parts supplement that would have the specs on mounting these?? Template?? Thanks

This is from a Demon hood. I'd love to see the measurements from a Twister hood to see if they are the same.

Thanks, I went over to my buddies and all those # 1 holes were there..Install completed looks great..
