See if you can get the parts diagram from calling support at either of these websites:
http://www.repairclinic.com/
http://www.appliancepartspros.com/
I tried entering your part number in both of these sites and nothing came up, so I don't know how much luck you'll have. However, when my old 70s GE washing machine tub boot failed from decades of use, I was able to get it from appliance part pros by calling up support and asking them for help. The tub boot was a PITA to remove, and I ended up shearing my plastic agitator (because it became one with the unit over the course of decades), but it actually worked and I got a few more years out of it. Luckily, GE reused the part for many years so there was a cross reference for the part. There is a good chance your machine is compatible with parts of other model year Whirlpool machines.
