Also sourced a Buick 300 water pump that I've been needing and when I looked at it compared it to the Rover pump, I realized it wasn't even close. It seems I had a timing cover that was only used a year or two on some Rovers and would put the water pump up too high. So after a brief search, found a Buick V6 timing cover that was just what I needed. Now to get the gaskets and put all this together.
