Sorry to read about the accident.
The new Classic Motorsports issue has an ad for the new frames. No price listed.
As for the wheel, is it really torn up or can it be repaired? There are numerous companies who will repair alloy wheels. I believe they weld in new metal and turn it on a lathe to reshape the rim. If the center is bent they won't repair. If it's too far gone they won't work on it.
If you are still planning to sell the car, maybe you should get an estimate and reduce the price accordingly. You wouldn't have a claim so it shouldn't affect your insurance rates. The risk lies in finding a buyer who is willing to purchase the car knowing it needs some specialty work before it is road worthy.
Years ago the son of a local chicken farmer ran a red light and hit my first TVR. This was in Vineland NJ. Apparently the kids parents were "connected". I insisted in a court hearing.
As usual traffic court was packed, and I was way down on the list of cases. I paid a lot of atention to the cases that were heard before mine. One involved a local police officer who ran a stop sign and was hit by another car. The policeman wasn't on a call, his lights weren't flashing and his siren was not on. He just wasn't paying attention. The judge was extremely biased toward the cop. It was obvious that he didn't want the city to have to buy a new police car. (it was T boned and totalled). He had the civilian take the stand first to give his account of the accident. When the driver said the cop car pulled out right in front of me, the judge stopped him and said "you saw the police car?" The driver said yes. The judge repeated the question and said you saw him before you hit him. The driver said yes, I couldn't avoid hitting him. The judge said the driver had the right of way, but only if the intersection is safe and clear. Because you saw the police car and continued on, the accident is your fault. Amazing but true. No matter what the driver said the judge wouldn't change his mind.
It was another hour or two before my turn came. The judge said he had both of our statements and there was no reason for testimony. There was no clear violation on either side as we both claimed to have a green light, so we had to settle up with our own insurance companies. I said I wanted to ask the other driver some questions. The judge scolded me and said there was no reason to do so. I insisted. He said I would have to take the stand first and that "anything you say will be held against you". I gave my account of the accident. He scolded me again for wasting the courts time, saying that my account was exactly what was in my written statement. Again he said we both needed to go to our way and settle with our own insurance companies... I insisted on having the other driver take the stand. I planned to ask if he saw the car (just like the judge asked that poor guy earlier). The other driver took the stand and said the light was red as he approached the intersection, but he could tell it was yellow for the crossing traffic. So he didn't slow down. He was expecting it to be green by the time he reached it. Then he saw the little red car in the intersection. He was driving a clapped out '63 Impala. Said he tried to brake but the road was wet and he skidded into the car. The judge gave him one of those looks where you roll your eyes in frustration, called him by his first name and said I'm going to have to charge you with the violation. The kid said "I saw him and couldn't stop." The judge said it was his fault. It was obvious that the judge was mad at me. Both for having out smarted him and for getting his friend nailed with the ticket.
I don't know if this tactic would work with an honest judge but it worked for me.
It took 4 months to get a check for the repairs.
