The 1981 onwards dashboards appear to have the 3-pin regulator as can be seen in the attached image (not mine, grabbed off the web).

While I can't see what the actual numbers are on the OEM 3-pin regulator, it does appear to be effectively the same as a standard 7810 1.5A regulator. It is Volvo part #1362674 - available from Skandix for the scandalous price of €28 for what is a common, generic 20p part if you bought them in any bulk. (Though it is possible that the Volvo OEM unit has extra surge/transient protection circuitry built in because it is a little fatter than a standard 7810).

some of the 300 series cars had the 3 pin electronic regulator which plugged into the flexible printed circuit board ,
