Parts to connect to Titan vertical grid model #582090

I have a Titan vertical grid model #582090. Some connection parts are leaking and need to be replaced.

A) I need Nut # 51013000, 3" dia to a 1 1/2"  pipe. B) body union male 1 1/2 87202400. Would it be fine to connect to the filter?

C) I also need the Top mount valve assembly 6 positions and 6 screws, 7 3/4 dia for 1.5" side mount valve 51000111. Also need the Lig-o-ring and spider gasket.

Would all this be able to connect to my filter?
