On Hold (need help) T-Series Cabrio

This is my first mod, so it'll probably take me a long time to make everything the way I want it to be.
Help is appreciated.

What I'm working on right now:
-filling in a gap in the back of the truck
-the jbeam

It's just a regular T-Series with a chopped up roof, for people who want to enjoy the breeze while delivering stuff to warehouses.

Hey, this sounds interesting! However, please show a picture of your progress, as we just want to know how it looks

 

Almost like Jeremy's Sports Lorry.

 

Lol, the Burma Special Top Gear

 

I'm also trying to export a jbeam file but all it does it this:
This is the reason:
I can't deselect it, therefore the plugin exports a jbeam file of the headlights frame, not the entire truck. Can anyone help?

 

I tried it again and it still happened.

 

How difficult can it be to press A once or twice, or click on the empty space to the left side of the part name?
