Yes Erik same principle. Just add some character to the model.
Now to finish up the under carriage.

Install the 4 rear shock absorbers. Side of the hull to the differential.

Next the rear sway/stabilizer bar. Mounts between the rear differentials.
]
Next the rear grille panel.

Support bracket for hitch and tow eyelets are next attached to rear grille panel.

Before installing the exhaust tailpipe, i finish airbrushing the OD over the under carriage.

The muffler is burnt metal and a wash of rust.

The installed right under the grille panel.

Next up, getting some interior work in.
More to follow.

Great job on that muffler!

Now start work on the interior. The side walls are white and the floor is OD.

Before painting will start with some basic. components. First with the rear bulkhead/firewall that separates the interior compartment to the engine. Side note, plenty of room in the engine compartment if one wanted to have a resin engine installed in place.

RH side panel which also has the storage compartment door molded in place.

Radio shelf mounts on the LH side of the fighting compartment.

A PE panel is attached to the to of the differential hump that juts up from the floor.

The shifter console with the e-brake handles is then place between the front seats.

A pair of storage boxes are placed at the rear LH/RH rear side panels in the fighting compartment.

Next a PE flash light holder bracket is attached on the RH side wall towards the co-driver.

Next is to paint the side walls Glossy white using Tamiya Acrylic. And the upper structure sides as well.

Next to add more interior components.

More to follow.

That is good use of a few PE parts - they make a real difference here IMHO.

Your Greyhound is building up very nicely, Chuck. The Tamiya M8 is another model in my stash I would like to get to soon - this an inspiring project for me. I don't think I've seen one built with the steering mechanism add-on. With the dynamic look you will achieve, you could put it in an interesting diorama. I had a lot of fun with the PE for my T-72. You are right that armor is the perfect subject for PE application. In addition to the kinds of details it mimics so well, the flat planes and walls of an armor model, inside and out, give it something to securely adhere to. I had a heck of a time with PE until I learned how well it glues on with a drop of Future. I find Future will flow beautifully under metal parts with a fine brush applicator and almost disappears from view when it shrinks up after drying (and it self-leveling as an acrylic). Since I also have need to fix the positioning of PE after it dries, a bit of Windex will melt away the Future and allow me to do this.

It's amazing at how much better these tiny PE parts look, when they are added to your Greyhound and then painted. It takes your model up a notch or two for sure...and gives your build details that can not be achieved right from the box. Then you articulated the front suspension and now the front wheels are turned. This also was a great idea and it makes your M-8 look even more realistic. I think that Colin is onto something there with his comment about how nice it would look in a diorama. However building something like that is out of my pay grade ! I have never attempted a dio. Maybe someday...

I'm looking forward to your next installment and the 3D decal instrument parts review was a nice read too. Your Tamiya P-38 looks even better with those additions.

The floor is painted Olive Drab. Looks rough but then it will get scuffed, muddy, bloody and quite worn out during heavy use in combat operations. So I am not to worried about the brush strokes and unevenness.

Next the seats are painted first with the seat backs, which actually fold when not in use.

Then the seat bottom cushions are then installed.
