Difference between L & R lateral control arms (front)

[gprix1]

I went to reinstall my front lateral control arms on my 2g GSX after installing aluminum subframe bushings and now I can't tell if there is any difference between them. Most parts have a L or R somewhere on the casting but not these. I started to think maybe they are the same but then I looked them up in Mistu' ASA and they are actually different part numbers.
Does anyone know how to differentiate between the two? Perhaps the way the pivot holes are angled or something?

Thanks for the link turbosax2,
I did a lot of searching and found nothing of any use.
I'll compare mine with those pictures tonight. It appears the differences are very subtle so I will definately mark them L and R once I think I've identified them correctly.
