911 Interior black paint for dash and exterior black paint for suspension

[Martysentme]

I am restoring my 1973 Porsche 911 T and wanted to ask which black paint is suitable in color and sheen to repaint the dash, interior door perimeters and bits like the seat rails and rear seat belt mounts.

For the parking brake components and pedal cluster..are they the same color/sheen?

Same question for the suspension components. Did Porsche use the same paint or did the color/sheen vary between interior and exterior parts?

My preference is a 2 part paint product over epoxy primer. The suspension components will be media blasted prior to primer.

It seems POR 15 is a common option but it's not for me.
