I'm looking for either a 6T or a 6AL box, presumably used (my max is $100). My goal is a rev limiter of some sort... I have a 6A box (w/ no rev limiter), and a "Soft-Touch Rev Control" p/n8738 (for a 6T box) - and of course they don't work with each other. Whichever setup I find first, I'll be selling/trading the other bits I have.
