I have a '70 C10 LWB stepside that I bought in 2001. Took 6 years of plugging along doing work on just about every part of the truck until I had it "completed" in 2007. It isn't a trailer queen but turned out pretty nice for a back yard resto and I am proud to say that I did it all myself. You can get almost any replacement part you need from LMC and other vendors and don't forget to check Ebay, too. I got a brand new dash pad for mine on Ebay at a very decent price so it pays to shop around.
The restoration will take time so don't get discouraged. Whenever you feel like giving up or feeling like it will never come together just take a step back, catch your breath, and as said, work on small parts that can get done pretty quick so you can actually see some progress being made. When you finally get that baby finished you will be glad that you stuck with it.
We all look forward to seeing some pics of your truck and the progress you make.
