you buy a manual and read the section referring to head gasket installation.
Its probably around $500 mostly because of the amount of labor that it takes to replace it. However if you just order the gasket from the auto parts store and replace it yourself it'll only cost you $20.

To replace the alternator in a 1980 Datsun pickup, first disconnect the negative battery cable to ensure safety. Remove the drive belt by loosening the tensioner, then detach the electrical connections from the alternator. Unbolt the alternator from its bracket and remove it. Install the new alternator by reversing the process: secure it to the bracket, reconnect the electrical connections, and reattach the drive belt before reconnecting the battery.

depends on the engine. but usually passenger side closest to the radiator, furthest from the firewall
The voltage regulator on a 1980 Datsun 720 pickup is typically located on the inner fender well, near the battery. It is a small rectangular metal box mounted to the fender or firewall, often close to the alternator. Make sure to check the wiring connections to ensure they are secure when inspecting or replacing the regulator.
