got my kit in and was wondering if any one had this problem. the instructions show a pass through hole in the core support. i don't have this. does any one know where the hole should be. don't want to screw this up, there are pre-bent hard lines that go through there.

also, the allen grove brackets that came with the kit aren't even close to fitting over my headers. did any one have this issue.

thanks in advance
