Josh, as you learn your way around in the site here you'll find that its better to ask questions in the most appropiate forum for the best results. Not everyone visits here in the Welcome Center so folks miss out on the knowledge of a lot of folks. For example your question may best be answered in the General Truck talk forum or probably the Driveline forum. If by chance you get a question in the wrong forum a moderator will sometimes move it for you. We want to help you all we can.
As for parts I think you can find most of what your talking about at your local FLAPS. (Friendly Local Parts Store) Examples would be Advance Auto,Auto Zone,NAPA. If not in stock they can usually get the stuff overnight and best of all is there is NO shipping charges.
You may also want to check out the Links section here at the Bolt. A couple vendors help support the Stovebolt site and even offer a discount if you make a donation to the Bolt.
AS always, check with several vendors before making the buy. You can find some buys but you have to check'em out.
Hope this helps in some way.
You may want to just rebuild the slave unit you have since the truck is in pretty good shape. If so, and you can't find it locally you can get a kit here
http://www.oldchevytrucks.com/cart/index.asp?sdes=clutch slave for about $20 bucks and JimCarter usually only charges actual shipping.
