if you cut the hole right along the line "where its double walled" of the hole already there, in the second pic you should be close, that hole is way to low
As YEAHLOH95 said, the hole shown is maybe an inch low?? anyway you might have to trim the inter well material just a little... I also hadto cut into the double wall area a little to line it up. It will depend some on you MAF setup(lenght). To bolt to the fender mounting bolts. I used door trim around the hole.
