Jay,
Check autokrafters.com and dearbornclassics.com to get an idea of replacement parts, patch panels, etc. available.
Also, the Fairlane Club Fairlaneclubofamerica.com has been an excellent source of knowledge and parts over the years. Doug Bender, a forum member is the President.
Kevin Marti of Marti Auto Works sells a number of resto parts and bought Ford's production database from 1967 to I think 1976 so he can tell you for a fee the exact pedigree of your car. If you tell us the partial VIN (we don't need the last 5 numbers, those are the sequential unit numbers) and door data plate info many of us in the forum can tell you the date and location of production, the original engine, transmission and axle it had.
Like Barry R said, they are reasonable in cost and IMO a good way for some to get started in the hobby!
