First, sorry that I seem to spam the forum lately with all my questions but you guys have been of great help so im using you as my best tool

Ok im probably doing my last orders for whatever im missing for my cab. I already have my buttons parts including a wrench and my 2 8-way joysticks.
Here is what I think should be the only parts left to order. Tell me if im missing something.
from Ultimarc:
- I-Pac 4 = 65$
- suzo/euro stick for my 4-way = 14$
-wiring kit ? = 19$
from Ponyboy/Happ:
- T-molding (how many feet should be enough/safe ?) = ?
- Happ usb/ps2 trackball = 80$
- Happ trackball mounting kit = 11.95$
I am not putting a spinner in. And is it good to get a wiring kit such as the one from ultimarc ? Is there any less expensive ? I think getting one should be good as everything I need to wire the CP should be there...
I want to save on shipping so if 2 orders max can be done that would be good.
Any toughts ? Missing something ?
