First welcome to the site - hope you find the information and support needed for you concours focused restoration projects
There are many threads showing restored front suspensions. So if you find those it will reduce the need to post pictures again. Basic outline
Tie rods - Darkened (heat treated) main bodies. Machined caps are brighter due to the forming and machining. Studs a lighter (than the hardened body) machined finish all oil coated
Spindles - dark heat treated surface with bright machine highlights - top & bottom as well as outer surface of ball joint attachment points. Brightened spot at hardness test (from grinding) Bright machined surface and clean up of sides of the tie rod attachment arm. All oiled
Center link - dark heat treated finish main surface with bright freshly machined surfaces.
If you've sand blasted the parts you've got some work in front of you to get them back to looking original but it can be done
So do a search and check the library for those previous topics and articles. Check out subjects related to phosphating, tumbling and gun bluing
If you still fall short in your needs or understanding post again and we'll try and help
