rebuild details

officially began rebuild. transmission will be done in about 2 weeks. engine reboring and rebuild is scheduled to begin in about a month. my goal is to have it going down the road by next spring. since it has not run in about 10 years, besides some body work and details, what all should I plan on rebuilding and/or replacing. if I am going to all the trouble of new engine and trans, should I just plan on starting new with all other items? I am thinking about: water pump, starter/solonoid, carburetor, alternator, coil, fuel pump, etc. what am I missing? also, a fuel tank that is now 50 years old and has been sitting for the past 10 years....... thanks for your input in advance.

When I'm doing a rebuild like this I always replace things like fuel pump, water pump, hoses, and belts. Alternators and starters either work or they don't--if working, clean them up and use them. Solenoids and regulators get replaced--both cheap parts. You didn't mention brakes, but when a vehicle has set for many years this is always an issue. With brakes, I always replace wheel cyls., pads and all rubber hoses/lines. Brakes always draw water, so if you suspect internal line rust---replace steel lines. Stopping is more important than going. When re-building these old cars, a few hundred dollars spent can eliminate tons of future issues.
Good Luck Mike

Get the gas tank cleaned out.

Go over the wiring.
