Might consider adding a Avid billet chain case cover before ya button it up. The 08 plastic covers had issues and even with the update stiffener bracket and gob of foil it was still cheesey in my opinion.
I also added a spring tab to the compressor and a couple exhaust springs to hold the unit to the tank. If your kit is new, this won't be an issue. Just the older ones.
I would also be getting some duct tape or plugs on the intake and exhaust before you do any drilling or grinding.
This is the left front motor mount bolt,
some boosted sleds were breaking these. Might want to replace it with an ARP bolt like
this one.
If the new kits don't come with the intake boot bracket you'll want one of them too.
Good luck on your build. EW
