you must remove all the bolts from the firewall under the hood and drop it all, seal with clear sillicone after all done... can be found at any 99c store.... just as good as kragens.

theres a couple studs with nuts that come through to the outside of the firewall. the inner fender is in the way of getting to one of them.Theres no need to take the box off of the outside. you just need to pull the heater box under the dash. First thing to do is unbolt the glovebox door and get it out of the way. then you can get a better idea of where the studs are that go through the firewall. the hardest part is the bottom stud that the inner fender is in the way of.
