For years I've understood all that was needed to convert between LHD and RHD was to loosen the 3 screws behind the lowbeams and rotate the housing. However, some believe that the RHD spec projector is different altogether because it has a different part number. So I ask, if anyone here knows if this is true. Is the RHD reflector/projector in the UK any different from the LHD found in Germany?

Reflector/Projector are two completey different headlamps.
Only the Projector type can be "Turned" to either LHD or RHD. The reflector type cannot.
In all the years i have been "into" E30's i have never heard of not been able to convert a LHD projector to RHD or vice versa.......
The main difference's between projector headlamps in "Smiley" & "Non-Smiley" and either Bosch or Hella.....

three types of lights for E30.
1. bulb and reflector - not changable from LHD to RHD
2. projector light that uses a lens to direct the light, these are called smileys or bulls eyes (or euro lights for you accorss the pond), they are both the same with a slightly different back plate that gives the smiley. these can be converted LHD to RHD as you describe above
3. sealed beam - US (and old Japan) only lights, they cannot be changed.
as for there being a difference between left and right hand part numbers I am not sure.
easiest way to see what you have is for you to post a pic of the front of your car (or look at the wiki page for DIY smoked lights, this unit is a projector light and this is the only type that can be swapped from LHD to RHD

Hi guys, I am aware of the different lights. I used the term reflector because in the ETK that's what they refer to the projector as. Removing the 3 screws to adjust the projector between LHD/RHD is well known, however, someone pointed out that there is a specific RHD (UK spec) projector since there's a different part number.
