ok guys i got my LQ9 and i wanted to use an LS1 intake and all that stuff but then i got my bracket and i noticed the whole wasn't there for the alternator.
(barrowed this picture from another site.)
So i said well the spot is there why not make the whole. I was scared to death to do it but if i wanted to use the ls1 intake and all that good stuff so here are the tools you will need
a drill
i used 3 bits one small for the pilot hole one a little bit bigger and then an 11/32 bit
a 10x1.50 plug tap
So what i did was bolted the bracket on with the bottom bolt
and lined it up
I took a very pointy pencil and lined it up in the center
once i marked it i measured how much i needed to drill
