As an amateur, and after many years of restoring my '67 Impala SS, the following 2-major issues come to mind, 1) Develop a good “overall process” time-line and don’t start buying new parts or restoring major sub-assemblies before you can use them. Sometimes, as good as you plan, you make changes. I was going to go with the original gold on gold, and I ended up purchasing a gold interior kit. The kit sat on shelves for several years getting “shelf worn”, and I ended up changing to Marina blue on black. That change really cost me in the end I convinced myself that I had to do it, and 2) DOCUMENT, DOCUMENT, DOCUMENT! You think you are going to remember where that ground wire attached to the firewall. You won’t. My restoration took so long, I had parts, fasteners, etc. all over the place, i.e., in different garages, my cellar, my bedroom, etc. Bag and mark everything, take as many photos as you can when disassembling, keep everything in a single location and segregated from everything else, and you will save so much time and frustration when it comes time to reassemble. I bet I spent over 100 hours looking for my stuff. In fact I bought many small items twice, and still haven’t found the ones I bought first. Good luck to anyone that is going to commit to a project like this, I don’t regret a minute of it!
