Sierra Trim Level Options

[SCHRUMGMC]

I am doing a Check List, on what I need to Clone my Grandfathers truck and I need y'all's input on some of this

What all did the 1971 Gmc Sierra Trim level's normally come with
Did this come instead of the Gmc 1500 V8 Badge ?

I need help figuring out what Trim I need to Clone my pawpaws truck, I have the Inside almost down pat..Did the Sierra's come equipped with the RPM Gauge, or the Vacuum Gauge ?

Also how far away does the Sierra Badge go on the Sidemarkers
and Cargo Lights normally came with these trucks...My pawpaws had a Bed Cover on it, anyone know the maker of these? Leonard I'd assume..







On my pawpaws below what type of Badge does that look like on the Sides
