What works best to install a threaded insert into interior plastic so that you can then screw in a threaded screw? Jack nut? Some type of rivnut? Looking to install a net or strap over the little cubbies in my Gen 4 to make them useful, and possibly some small hooks or anchors on the flat ledge over under the cargo area glass. Also, how easy is it to pull this plastic piece off to access the rear, and what type of screw on insert would work then that’s a two-piece screw together that creates a screw in anchor point? Thanks!

I've had trouble with rivnuts not catching in plastic.
I think with a dedicated tool it would work.
Bearing that I wouldn't count on the wood style T nuts to be able to hold much weight.

For putting brass threads in thin plastic.... I reach for a rubber EXPANSION NUT. (aka WELL NUT)
After punch/drill a hole in the plastic...push the EXPANSION NUT into the hole. You now have threads in the plastic.
As you tighten down the screw, the rubber e-x-p-a-n-d-s to grab the rear of the plastic. (DO NOT overtighten!) They hold VERY well.
EXPANSION NUTs can also be used to seal holes in plastic containers.... or when you need vibration-dampening. You can even push an EXPANSION NUT into the end of a pipe and snug down a screw to plug that pipe.
The only 'drawback' is that you need some 'clearance' on the backside for the EXPANSION NUT to do its thing.

You want a soft anchor device that will retain compression against the plastic, even if it’s abused - anchors are pulled hard and in different directions. Well nuts are ideal for this:
