    it aint that hard, you'll need a pitman arm puller (either rent or buy), socket, ratchet, extensions, (or an impact, makes life alot easier). Hardest part is separating the tie rod ends from the pitman arm. It took me a couple hrs to do the swap, and that included adding a steering box brace at the same time (If you dont have one, I would recommend it, also check for cracks in your frame). Next hardest part is holding that heavy thing up there while trying to start the bolts back into it, or not drop the old one on your head /forums/images/graemlins/crazy.gif (may want a helper).

    BTW, where in NC are you?

    At some time (I'm not sure of the year though) Chevy started using different lines to the box. You may need to swap lines also. www.partsamerica.com shows 2 different part numbers for the 75 and 82, so maybe the difference is the lines(or maybe something else. /forums/images/graemlins/confused.gif)

    You are correct. They made the switch in 80. I believe pre-80 are metric fittings and post 80 are standard. They may be the other way around but that is what changed.
