buy lot's of zip lock bags and sharpie markers, rubber made totes (organization) bag and tag everything!!! I can't stress that enough!!! I bought a "Basket Case" '71, and even though the Previous owner did a great job keeping most everything together as it came off, I still had a devil of a time identifying hardware and smaller pieces that I needed or were missing.
taking pictures before disassembly will save you a lot of head scratching time, as well and having to ask questions here, although, you will find that most everyone here would be more than willing to take a moment to oblige any request. if you have a "harbor freight" store within driving range, or even buy online, those welding "Butt-Clamps" for welding sheet metal are a god send. you can't have enough them. I bought 20 to start, and bought another twenty after a day, just because they were so handy. A "Uni-Bit" (step drill bit) kind of looks like a "pine cone", those are handy for spot welds, but I bought a set of "Roto-Broach" hole cutters, basically bigger heavy duty spot weld/hole saws... I forget how much they were, but very handy. Vise grip welding clamps, many small ones, but sometimes you may need the bigger ones, even the long reach ones, depending on what you have to repair/replace.
I rented a pressure pot sand blaster, and borrowed a pull behind diesel air compressor from my work (nice to have that resource available) and I bought 600 pounds of crushed recycled glass to blast my chassis and other parts. crushed glass is safer to use than sand, and it's cheap....about .13 cents a pound!!! I think I spent $65-$70 for the glass, and $20 on diesel fuel and a day of my time and got it all done. Before I started, I set up a "Berm" or containment area out of Poly sheeting to capture the glass/rust , etc.... and made a sieve out of a 5 gallon bucket and some window screen to strain the glass from the debris for reuse....worked out pretty good.
I also bought a small "Harbor Freight" Baking Soda blaster, to strip some of the body parts. I'll tell you this, that stuff gets everywhere, but, once I you start blasting with it, you'll appreciate it very quickly.....the spot welds show up almost immediately, and look just as they did going down the assembly line before paint.....you can still see the burn or discoloration from the spot welders in the metal, make drilling them out a cinch. You'll have to read up on using baking soda and the clean up of the surface contaminants, there is a special wash solvent that makes this a breeze, I forget what it was called.....
another tool that would be a worth while addition is a set of Cleco's (spring loaded sheet metal clamps) these you insert into a hole you drill through both pieces of sheet metal and it holds them very tightly together. buy lots of these too.
I'm sure I'm forgetting something, but one recommendation with regards to mig welding wire, use the .023" inch stuff with shielding gas (Argon/CO2 mix) a lot less grinding, (ask me how I know) any way's, good luck with your build!

p.s. I think I have around $15K in my build total, and I did almost everything except the transmission and paint......
