Make all the bolt holes a little larger[makes up for the angle as the bolts protrude from the snorkel],use locktight on the studs in the snorkel,get some sikkaflex for the sealant[use heaps] I used a stainless self tapper to pull the collar into place on the body[instead of the rivett]. Finally I used a cutout piece of heavy duty fly screen mesh[the black painted wire stuff] behind the intake grill--stops the bugs. For the large cut out used the hole saw and dremmel blade and grinder, then painted all the edges with a jointing compound. Have fun and double check your work before you drill,make sure the template is neat on the panel near the windsreen pillar...
