LOL dude they are triple only 05 up ITR is single conetriple cone does not fit dc5r 5th and 6th only double cone. triple cone is only on 1 and 2. the cone is not the tabs on the steel ring it is the breaking surface. no triple cone 5 and 6 unless you have custom gears made for it. 01-04 dc5r used double cones 5 6 and 05-07 used single cone. no triple. the synchro is the same one that is on 3 and 4. triple cone synchro will not fit dc5r 5 6 or any honda 5 and 6 that i know of. if you have an extra synchro from 3 or 4 you can use that on for 5th and no problems.
