i am pretty sure that the FRO will drop right in. the only way it wouldn't would be if the trem was the cheaper schaller styled trems on the "10" series. considering that you have a dk2, it should be a jt580lp, or jt500. the jt580lp will look exactly like the lo-trs2, as the jt500 should look like the old trs or the washburn 600s. all of which are takeuchi trems. i have done FRO to jt-500 and jt-580lp swaps on jacksons. on a dr-3 and stealth ex, and the takeuchi routes are larger than that for a FRO. my only bit of advice for that would be to swap out the pivot posts for the ones for the floyd, thye work a lot better for the floyds knife edges, but is not imperative. i know that ibanez uses the same ones as floyd rose, but jackson uses some oversized ones, which are ugly as hell.
