Wanted to add this about the rear speaker covers. I essentially duplicated the recovering method that I used way back when I was working on my 87 GT. The grilles are heat welded to the interior trim and if you try to remove them they will break the plastic pins that hold it in place. Here's my solution to the problem.

When you pull the grilles off this is what you will see, first the holes that are left in the trim piece:

The larger round hole is for the upper seat belt attachment. And the back of the grilles look like this once the existing fabric has been removed:

Here's how the plastic pins look:

There's no easy way to re-weld these back on so a different attachment is required. On the face of the grilles there are four small dimples that are over-top of the pin locations on the back. These are a result of the injection molding process and fortunately show the exact positing of each pin. The dimples can be hard to see but are visible in good light. I ground the pins off smooth on the back side and marked the dimples with a sharpie marker.

I the drilled out the dimples to suit #8 machine screws on the drill-press. I'm suing screws with a tapered head and need to flare the holes so that the screws sit flush with the grille surface. To do this I used a conical grinding stone in my dremel:


And carefully using the dremel on a low speed I matched the hole to the tapered screw:


The screw are then held in place with nuts on the back side:


After a test fit the grilles were then sprayed with a black self-etching primer and were left to dry overnight:

I purchased some grille cloth from Rodney Dickman, it comes in two rectangles large enough for the front speaker grilles:

And to attach the cloth I coated the grille faces with 3M spray adhesive:

The fabric was laid onto the grille after the adhesive was applied and carefully positioned and stretched so that it lays flat and smooth at the corners. Heres the back side after the cloth was attached:

And after the trimming to size:

The spray adhesive is very tacky and the cloth sticks to it right away. Make sure your work area is clean.
I then used a heat gun to run a bead of glue along the back of the grille and folded the excess cloth over the back edge:

The grilles were then inserted onto the trim piece and attached with nuts.

And the extra screw length was cut off and the nuts secured using Loctite.
