Richard - I believe that the stock water pump has a pressed-on pulley, and that this makes the DMC pump unique. I may be wrong on that, but ... In any event, Darryl Tinnerstet (http://delorean- parts.com) has a custom pulley that will allow the use of the more common pumps (common usually equals cheaper) for the Volvo applications. I helped a friend change his pump out with one of these, and it fit perfectly. You may want to check into that. Also, please email me privately regarding some of the other points that you made.

If I go with a CarQuest water pump (I called them last year and they said they had it available, so I may luck out there) will I need to buy the pulley seperately, or will this come with the part?
