A fresh battery, a small gas can and rubber fuel line (in case you need to gravity feed the carb), some electrical connectors, wire, crimpers, ect., maybe some plug wires in case rats have gotten to them, engine oil, coolant or water.
Both my big bolts (56 4400 and 59 Viking 60) had not run in 5 to 8 years, and with those items above, I got them both to run and drive, but they both still have no brakes...Good luck, be patient and have fun! Send us some picturs and let us know how you make out!
