There is a tee joint in the cooling system that requires 3 clamps on my 2002 Polaris 700, the part numbers are 7081047 (qty 2) and 7080826 (qty 1). The 7081047 clamp is not available anymore it looks like, is there a way to determine the size and what a good replacement would be?

The guy that had it before me replaced these with screw clamps, but they loosen up and allow coolant to leak.
