Grover Locking Tuners: Any place to buy individually?

[SausageofPower]

I snagged a BC Rich about a month ago, the double neck Bich. I wanna throw locking tuners on her/convert the hardware to black, but the 6 in a line tuners on the 12 string neck I can't seem to find as a set that don't have the angled tab on them. So...does anyone know where I can either get the 6 in a line 502BC's with a straight tab or buy individual 502BC tuners?

Thanks!
