All shiny metal parts that you see are old one.
They were not broken, just used for 20 and more years, dirty and little bit rusty.
First cleaned with electrolysis and then zink galvanized (electro plated with zink)
All door locks, rear door spring with hand, front bonnet lock, internal door handles.
That is why they look so shiny.
Black parts around engine bay and inside the car are additionally powder-coated
And bumpers are also powder-coated
very few parts are brand new.
I have 2 donor cars aside so using best part out of three.
