75 164's came with a wider tail light with more red in it, if that makes sense. they are shared by only 75 164's and 76-77 264's. What that corresponds to in 4 vs 6 light I dunno, but the 164 lights are bigger. You try rpr?

The link below will take you to a local Volvo repair shop here in town.

I have no doubt that he will have what you need. I don't know how reasonable he will be....

Conversion: not without cutting out the required sheetmetal from a donor vehicle and some good welding and spraying.

However, the 4 panel lights are identical, as far as I'm aware, to the ones used on the '73 onward 14*. I think you should be able to get them without too much trouble, there must've been hundreds of thousands of these assemblies made. They're quite ubiquitous around here, if you're really in a bind you can get them from here (the Netherlands) by airmail in a matter of days. If you're prepared to pay a little more it would probably be possible to find new ones (as in "new in box, never been used").

Isn´t the four panel light the same as all the 73-74 140/160 series sedans taillights? And wasn´t the 240 1975-78 sedans all four panel lights in the US?

If so, it can´t be impossible...converting to the six panel light is possible, however - just cut the required holes out, but may be a shame on one of few "untouched" old style 75´s. You do what you feel like.
