2004 T50 waterpump kit

[1234ward]

local dealer sold me the wrong kit
I found I can order the correct one here for half what they charged.
I am also going to replace the lower housing and oil seals,
anything else I am missing?
Not too clear what is included in the kit(6H3-W0078-02-00)
thanks in advance

It is actually repair kit 4 that I needed, same mistake my dealer made.
Kit 3 and kit 4 are two different animals
I think kit 3 is for F50
