Some general thoughts on the build. Label MF Everything. Spend the money and get factory manuals. Ratchet straps are your best friends. The Shop-Vac is your second best friend. Using cutting oil when drilling is essential, slow the speed down don't burn out your tips. There are a lot of tools you can go cheap on, a tap and die set is not one of them! McMaster-Carr has every bolt You'll Ever Need. Yogurt containers make awesome bolt storage containers. When stripping out your donor vehicle do not throw away anything! Most of all my bolts came from the donor vehicle as well as cutting up sheet metal and frame pieces to make brackets. A cheap amazon.com thread finder set was extremely useful. Count all the cutting discs you think you'll need then multiply that times by about 20 if you buy them at Home Depot etc. My advise, buy the thin expensive ones at AirGas or another welding-specific supply store, they last a long time, don't make nearly as much dust, and cut faster. Do not try to use a wood hole saw bit, buy one specifically for cutting steel, don't ask me how I know that. Don't waste your time trying to modify an existing gas tank, just spend the money and have one custom-made.... unless you are a great welder that can ensure it will not leak. If you're going to do a project, take the time to make a complete plan with goals to accomplish each day. Be determined to accomplish each daily goal no matter how long it takes (build into your plan an entire day just to fix your screw-ups. Depending on your confidence, you may have to schedule more than one of those).
