busted blade

i have a trex 450 with a heliup frame which appears to be similar to the HDX 450. i was hoping someone could verify interchangability of the tail boom mounts in the frame. the HDX appears alittle more robust and i would like to use those parts if possible. the heliup mounts measure 30.33mm wide (inside distance between frames) and the bolt spacing is about 16.1mm center-center. thanks
