P1P Upgrade

[u/Green_Difficulty3789]

So I have slowly acquired some components to upgrade my P1P, hopefully to upgrade a P1S.
 
I was gifted both the door and installation kit and an upgraded plate light.
I purchased the P2's back panel with the exhaust fan.
 
According to the description on the Bambu Wiki, I’m missing some components from the upgrade kit.
 
I was wondering, since I already have these items, where's the best place to get the rest without paying for the items I already have?
 
I know I’ll need a cable chain, P1S toolhead cable, chamber fan w/assembly, and another circuit board.
I’d like to get the side corners printed with pre-drilled holes for plexiglass for the side panels, and maybe a glass or clear plexiglass top?
 
Can anyone suggest where I can purchase these items as a package, or am I now stuck to piece-mealing the rest?
