Aero Spacer Kit CP30/H31 on “old” Grizl

I have two questions regarding the spacer kit:

1. Friends grizl: Will this fit on a grizl 2023 Model with external cables in combination with the H31 Cockpit and Do I need the extension plug?

2. My grizl: On the endurance cf 7 (pic 1) the bottom spacer is different than on the grizl 2024 (pic 2, old grizl) with integrated cables. Is this included or anywhere available for a sleeker look? Might get the CP30 CX.

Thank you and sorry for the bad quality images.
