Uncle czechokeflavik,
You have options to replace the alternator.
Could you explain your 1973 Volvo 164 E alternator or charging system fault? If your 164 E still has the factory configuration, you have a 35 or 60 ampere alternator with a remotely mounted voltage regulator on the North American passenger side inner fender behind the head light assembly.
It is very likely these components have been replaced. Maybe not.
Alternator failure can include mechanical failure by seizing (the rear bearing, usually, unless the drive belt was set too tightly too often or a failure to charge (many causes, usually the brushes have worn down and require replacement or the remote voltage regulator has failed).
Your 41 year old 1973 Volvo 164 E may have been updated to a newer alternator / charging system configuration with the voltage regulator mounted inside the alternator. Updates to the wiring harness may have occurred (versus what you see in the Volvo 164 OEM factory green service manual - I have one yet it is packed, or Bentley, or Haynes, and on down from there).
Do you have manufacturer brand and part numbers on the alternator?
If you have the factory installed 1973 Volvo 164e alternator and charging system, a google search reveals the Bosch (and possible SEV Marchal) models. Volvo sometimes used both a Bosch or SEV Marchal alternator and or a Bosch or SEV Marchal voltage regulator.
Examine the alternator on your 164. Discern at least the manufacturer and manufacturer part number. Next, discern if you have a voltage regulator separate from the alternator or not. If so, discern the voltage regulator manufacturer and manufacturer part number. If not, I'd be pretty certain your alternator is updated with built in voltage regulator.
You can update to an alternator with built-in voltage regulator. The B+ lead to the wire harness connects to the alternator directly no matter the voltage regulator configuration.
IPD and FCPGroton are of no help to you. What you can look for are Volvo alternators that come mounted on, say, 1972 ohv (overhead valve engines) like the B18, B20 (like in my 1975 244 DL), and your B30. The mount, I'm pretty sure is the same.
A search on Google for "1973 Volvo 164 Bosch alternator" (no quotes) reveals many pages of things like "Bosch AL77X - Alternator - Bosch" and Beck Arnley as either new and rebuilt alternators that should be a drop in fit into the bracket that carries the alternator and wire harness connection.
AutoZone (or I dunno what they call it on the East Coast in MA-state - Schucks?) sells Bosch parts very cheaply and you can ask them what they have for your 1973 164 E. You may also want to contact the Volvo dealership and ask them and get Volvo OEM part number. You can then use the Volvo OEM part number to research on tascaparts.com (see if the PN is superseded) and with Autozone if they have a drop in alternator you can successfully use in your 1973 Volvo 164 E.
You may want to inspect the rubber mount bushings that carry the long bolt the alternator hinges on as you tension the drive belt. Be sure the hardware is tight. The alternator should be quite snug, yet able to pivot with drag, as you tighten it, tensioning the drive belt, to the proper deflection.
Inspect the wire harness to verify the insulation remains damage free and not brittle or stiff. Replace as necessary. Observe obvious precautions and safety when working with charging systems and car batteries.
Finally, pay close attention to the short fuel line sections that connect the fuel injector rail to the six fuel injectors. These fuel lines can become brittle or the clamps become "un-snugged" (if you will) over time. Fuel can leak and can lead to a fire hazard. Many check the clamps and give a snugging up every now and then. I'm not practiced, so please research this and other boards for this issue impacting all Volvos equipped with the Bosch D-jetronic fuel injection system. (I guess you could have K-jet CIS; very unlikely.)
Carry an appropriate fire extinguisher with you in the car. I forget what kind. I think Halon extinguishers are no longer manufactured.
Research this and other 164 E specific issues on the brickboard and other Volvo 164-related boards like the www.164club.org, www.volvoclub.org.uk, www.164-140club.de/html/info_clubs_e.htm, and more. Search google.
Walrus3 on this board should have some good info for you.
Sorry for the long expository. I have to practice the qwerty keyboard else I lose it.
Questions and comments?
Hope that helps.
MacDuff.

Volvo 164e with M410 manual transmission (4spd+OD). Moon roof? Optional. I. Want. One. The B30 is an awesome engine! I won't ever consider the white block B3204 Porsche/Volvo hybrid of true Volvo lineage considering the many defects plaguing the engine (cast aluminum alloy block porosity problems the greatest fault, perhaps). I wish Volvo had not abandoned the all-iron alloy inline six when BMW and Mercedes have had decades of sales success and customer satisfaction with their inline six platforms. Volvo B30 - the truest of Swedish Rolling Iron.
