^^^^^^^^^^^^^^^^^^^^^^

you have a standard reverse rotation pump on your l31 , the truck is the same other than the hub and fan mount..
This was done, because of passed issues of people installing the wrong rotation pump on cars .. This set up, you get the pump and go that isn't the same..

I'll bet they make a pulley for the car pump that works with that whole set..
So you don't have to replace the pump.. as long as that pump IS a reverse rotation..
