    yeah the combination of that great article and the haynes manual make it a quite easy job..
    sure is a pain since you have to do a little in the cab, do a little in the engine bay and back and forth...
    but its worth it to get rid of that fishy smell in the cab...

    They're studs. The nut is on the outside.

    Take very carful look, there's a combination of studs with nuts, and bolts. Some you'll need to remove from the outside (engine compartment), and some from the inside. There's quite a few of them, so look carfully. There's also a nice hidden one thats difficult to remove underneath the blower box, outboard on the lower side on the outside of the firewall, in the engine compartment. Its almost in the fender...the article mentioned above covers it though...
