screw sizes for interior trim

[paradigm]

I need to reinstall a lot of my interior trim into my 86 SS Monte Carlo with T-Tops.

Does anyone know the size of the chrome truss head screws used for the interior trim? The screw I pulled from my rear lower and upper panels look to be chrome 1-5/8" truss head screws. I am thinking other interior pieces use shorter lengths? B-post covers, A-post covers, sill plates, visor brackets, T top roof plastic trims?
Is the thread pitch #8?
Other sizes are

What about a kit like this?

This kit is well worth the price. They come individually bagged and labled for each location in the car.

That’s not a truss head screw. That’s an oval trim screw with washer. Truss head screws are used on the lower B pillars in the door jamb

Number eight screw is the correct screw for interior trim. I bought some from my hardware supplier because I have several cars that needed them but those kits look like they could be pretty handy
