all of my Wammer Hoods and my Blowsion hood came pre drilled........ Ratti's 24/7 hood came without holes drilled, but I think it may have been a timing issue.........
I can see valid issues to both sides........
one thing to consider, the hood gasket you use can really effect the placement of the hoodhooks (Hull side) with the JSS original gasket, I had to raise up my 24/7 hooks, with the newer thinner JSS gasket everything worked out without any modifications.
With the FX1, you are talking about a whole different ballgame when it comes to gaskets, you cannot use the stock front latch with the JSS, you have to make a "Spoon" type latch for it to work (just pointing out how a hood gasket can really effect hood fitment)
