Junkman, post a photo of the receptacle in the power supply, and I'll look around.
If it's the three-in-a-triangle with flat cable, they are hard to find in good condition. Might as well buy new, or from Ebay.
My friend who bids surplus equipment auctions had dozens of Dell laptops but only half as many of those cords, when I took in my daughter to get her a dorm laptop.
Also, there is a recall for some of the S/N's of this power supply (photo) due to spontaneous fire. You might want to research that.
