    I would take the easier road and buy one of those adapter things that bolt on. I forgot what they are called. Quick! someone on MTBR must know before he welds.
    Leave no bolt untuned!

    A2Z, Brake Therapy, and MAYBE Specialized all make one. You'll also need a disc hub.

    How old is your frame? I had a '99 Stumpy FSR and there was not enough clearance for even 160mm (small) rotors from the chainstays so I had to stick with V's. If you have mate with a disc wheel just try it in your frame to see if the rotor fouls the chainstay before you start spending on parts.

    Billyboy197, a good point, before considering an adapter do all measurements you can, what you described is the most important. Once you get the adapter you are $40 in the hole and it may not work. In my set-up it worked but more by luck than my knowledge. One other criteriom is that the dropout should be flat, no welds and so on. My frame is about 99 Merlin.
