Hello to England,
the original hanging cabinets you will not no more get. With Ebay sometimes which are offered, these then too gotten require to much luck. Evenly because many T3-Dehler-Drivers search.
I had seen from IKEA in a T3 and did not find the solution not bad! One would have to shorten those if necessary in the length. Look at you the cabinets simply times!
