Which pump seal to order

Greetings,
I have a Maytag dishwasher Model#DWU9200AAX bought in 1993 and need to replace the pump seal and all lower gaskets/seals due to drip leakage. I have not disassembled the unit as it can limp along until I get parts to do the complete repair.

The question is whether the pump seal is the spring reinforced type or not. From parts breakdown:

"[AP4111632](http://www.appliancepartspros.com/part_details.aspx?part_id=4111632&rdr=%2Fpartsearch%2Fmodel.aspx%3Fmodel_id%3D29191%26diagram_id%3D683848"]Pump seal ( New Style No Spring )[/URL] - NoteAP204670 The manufacturer has changed the old spring design. If you have the old spring design replace with Pump module repair package part number

Does anyone know for sure which part to order?

Much Appreciated,
Bill
