correct parts to rebuild the pump part of a hayward tristar SP3202ASP

Hello,

I bought the SP3202VSP from you a few years ago and what a super pump it has been. Unfortunately with C19 I was not abkle to get to my pool for a while and the pump ran dry for some time and now does not pump so well but the motor sounds and works fine.  Can you check my list of parts that I think I need to buy to rebuild the water pump section.

union diffusert SPX4000Z1, Diffuser w/ impller ring SPX3200B3, Housing ring SPX3200T, Impeller with screw SPX3210C, pump seal HD PS4280, lubricant.

Are there any other parts I need / should get for this rebuild. Also, I am in the UK and you shipped to me before - I assume this is ok again.

Many thanks

Nick
