You can add rear disc brakes to H145 with a Australia-built R31 Skyline/Pintara setup. Fits over 13" steel wheels.

Remove the axles. Cut the axle bearing retainers and remove the axle bearings. Now you can remove the drum backing plate, and but more importantly will be able to fit the adapter over the axles. New bearings can then be fitted.
