I bought a 99 giant ATX DH for real cheap just for a weekend fun bike.

however the rear disc tabs are the old formula standard and are located on the chainstay and there is no way to fit any sort of adapter in there to mount a new caliper. what I would like is a blueprint or the mesurements of where the centers of the holes of international standard tabs are in relation to the center of the rear axel.

My plan is to put a 6in hayes on the back and Im a certifed welder so Im not worried about strength

thanks
