does anyone know what to use to mount left side rear panel (number 12)? It has no holes for plastic screws.

It's almost self explanatory, you do use 2 plastic screws were the rear panel and that panel comes together, the back of the panel itself has spots were they hang onto fasteners on the car frame then theirs the seat latch part that goes through that panel and a couple trim screws along the door. just look at the panel, like I said it's almost self explanatory.

 

Rear panel you describe is #24. I refer to #12 which has no plastic screw holes or rear folding seat striker bolt.
You mean plastic screws are attached in #12 from behind of the panel while in #24 screws attached in front of the panel

 

there is this kind of **** which looks like shaving blades but cannot find on ebay.

 

this is how the plastic screws are attached to the rear panel.

 

this is were the rear seat attachment goes through that panel.

 

no doubt about that but the panel i want to see photos is the one with the storage compartment

 

That is the storage compartment side(Drivers Side)

See those three rectangular slots,(along the top of the panel)those are for tree clips that snap into retainers that are on the body.
Is this for a 82? they seem to be a little different.than my 86(seat striker)

 

i have lost these retainers where i can find these/

these are what your looking for

 

yes i have these. But what will hold them steady when go through car's body holes?

 

If you look at the diagram you posted above,check your car and see if you have part nos. 3 or 31 (plastic retainers) in part 1

 

if these are like the reproduction plastic screws' nuts then cannot be used with retainer clips; clips diameter is larger than nut's hole

 

I know I was just using that as a reference,they should look similar or the hole itself will support the tree fastener.can you take a pic of the area were these will attach?

 

Many interior panels appear the same, however they actually vary more than most assume. Both by year and also options during the same year.

The rear individual or dual seat option includes strikers on both sides, however others include a single striker on the passenger side. I know this from the many times I have had to go around to drop the seat. (That and I just went out and looked at one of my Camaros.) Your diagram also shows the hole on one side and not the other.
Another interior example is that some include holes for the cargo shade and yet that position also changes over time. Because of that, asking individual people what their cars have does not always related to what you have. If you have parts from different years and/or options, then that can further complicate things.

The attachment points along the upper portion vary, but it looks like the same parts are used for all three. The one on the far left slides in and is actually the one on the wood surface. The other two twist into the slots via the cut in the top as shown below. The tree hooks into another plastic clip previously inserted into the body also shown below.
They tend to become brittle over time so if you can find both parts I would recommend replacing all that you can.

The link previously provided appears to be the correct piece.

Below are pics of original trees and retainers. The part that goes into the body is more yellow.

 

what do they call this kind of **** and who sells it?
