I ordered the scoop out of California... There were no studs that came with it, only bolts. But using the info from the link on the scoops I measured and drilled the holes where they needed to be, was a pain in the @$$. After drilling all of the holes the bolts did line up with the structural pieces on the underside of the hood. It turned out really good. I promised myself I wouldn't cut the fresh air holes until after the engine was rebuilt and needing all the fresh air I could feed it.. Well the engine is done and I need to cut the holes out, I will probably use "Year One's" gaskets they (rubber doughnuts) they sell. The biggest issue I had was drilling thru that perfectly good hood..LOL! After the first or second hole there ain't no turn'in back.. After the scoop was on, that's when I went ahead and put a big hole in the hood for the Hood Mounted Tach, something I know for a fact that was avaiable as an option from Plymouth, for Dusters & Valiants. The brochure listed it as "giving you that european flair".. So now I'm officially "flared"? LMAO.......
