Parts For WP Belt-Drive Washers
Unfortunately WP-US decided to discontinue almost all parts for these machines in the US around a decade ago, but because this design was by far the most popular washer design in the US [ during their almost 40 years of production ] there are lots of dealers, repair folks that still have parts and are selling them on Ebay etc.
All of the mechanical parts of the 24 " and 29" are the same right down to the agitators.
Major differences are the cabinet, cabinet top, tubs and baseplate. Many electrical parts may be different because of different voltages etc.
