What diff. in the 2000 Cobra "R" water pump.

What is the diff in a 00 Cobra R and a 99 newer Cobra water pumps? I heard that the 99 newer pump flow more. Is the Cobra R the same as the 99 up Cobra pumps? Will the 5.4 DOHC "R" pump fit on a 96 Cobra engine? Thanks
Here a link to the Cobra R pump on ebay.
