new project 1970 340 4 speed Dart

This sounds like the 1970 FC7 340 Dart that was listed for $5500 on Craigslist - San Diego. That posting is now removed.

Hopefully you already have a lot of the factory parts to renew the engine compartment, and the factory 4 speed (that car had been converted to an automatic with an automatic steering column - with battery in the trunk). What was the electronic circuit board mounted on the passenger side near the radiator and horn assembly?
