Help: Radiator Hose Part Number

[AKnowles]

I'm trying to find all the part numbers to replace all of the radiator hoses on the engine side for a 1999 Boxster. I think I have the hose numbers and hose clamps figures out with the exception of the heater hose return line (indicated by the red arrow in the Pelican pic). Does anyone know that part number? When I tried a search by part and/or number I kept getting the part number by the heater core int he dash area. And if I can get a bit of verification that I have all the right part numbers I'd appreciate that as well.

Here's what I have so far:

1 900-123-144-30 Crush Washer/Sealing Ring for Coolant Drain Plug (10 X 14 X 1 mm), Boxster/Boxster S (1997-04)
1 996-106-222-17 Water Hose to Water Pump (3-Way Hose), Boxster/Boxster S w/Manual Trans. (1997-04) (Purple Arrow)
1 996-106-501-07 Water Hose to Water Flange at Oil Pump Housing (Large Hose), Boxster/Boxster S (1997-04) (Orange Arrow)
1 996-106-502-06 Water Hose to Water Flange (Large Hose), 986 Boxster/Boxster S (1997-04) (Green Arrow)
1 999-512-609-09 Hose Clamp 32 x 12
2 999-512-589-09 Hose Clamp 25 z 12
2 999-512-594-09 Hose Clamp 53 x 12
2 999-512-668-09 Hose Clamp 49 x 12

Here's what I am missing:

Heater Hose to Return Line (Red Arrow)
Clamps



Note: I am planning to use the spring clamps (bought the tool to remove them so might as well use it)

Thanks!
