Remove the chrome from your classic carefully to avoid chipping its paint or breaking anything. Save the fasteners in labeled, plastic zip-lock bags so you won't lose them.
As you take the pieces off, label them with a post-it-note, clearly stating what the part is. For example, front passenger door handle.
Lay all the parts out on the floor and photograph them to create a visual record before you send them out. When your parts come back from the plater, you can verify that nothing is missing.
