Hey HiPSI,
They have to pay you what the parts cost new regardless of what you can find them for used or second-hand; they are legally obligated to (its in the Conditions part of your Insurance Contract) There job is to indemnify you, aka put you right back where you were before this happened. What if those $20 lights you bought from Pull-A-Part burn out, and cause you to hit someone crossing the street? Who's paying for that? Thats a major liability issue.. see where I'm goin with this?
Also, have you discussed with the claims people about the title situation? You know once a vehicle is deemed totaled or salvaged by an insurance company, you cannot register it with any of the 50 states, right? Might want to check into that before you get bent over
