1967 evinrude 40hp lower unit

[DPoco]

I have to rebuild the lower unit of my 1967 evinrude 40hp big twin. I have the selco book but cant seem to find the part numbers for the seal and gasket kit or the water pump kit does anyone know them or somewhere I might be able to find them? Thanks

Sierra Water pump impeller is 18-3083 If you want a complete kit with housing, you need to go OEM
Gearcase seal kit is 18-2686
