Mine was a L2500 tribute, I just looked, it was 17mm spacing / 68mm bridge, so smaller than I thought but wider than the Sub Ray5 I had. Maybe yours had a non standard bridge (maybe american custom, although I don't see them doing that as a custom thing), as looking on the net that is what the specs say.
Either way, he doesn't like the look of them so thats that out (and I understand that, I never really liked the look of a stingray 5).
