Hey I am planning to get the AC working in the Lancer and was wondering what items I needed to ensure I replace them. Looking for part numbers or specific enough that I can search Rock Auto or the like to get what I need. I know I need seals, but always fuzzy on the piece that is inline with the hose. And do I need to replace the expansion valve? Anything else?

I will be checking Rock Auto for the seal kits, but last time I think I had issues finding one at the parts store with help so not sure if I will find what I need with ease or not.

Thanks in advance!
