55.2-59 Comp help please

[Missyblue]

Hello all! I am reaching out because you have all been so amazing and smart and helpful and i really need help. I am sadly going through a divorce and my ex is coming after my Missy Blue truck. I built it myself with my dad and daughter and spent mostly birthday and Christmas money on it and gifts from family. Im worried because he says the like generic kbb sites say average retail 50k with no parameters and if he shows that in court I have to prove otherwise. I understand I have to pay for her but she's no 50k truck from the nicely fixed up stuff i see for that price with new engines and nice paint. I have reached out locally trying to find an appraiser didnt know if you had any other ideas or know of any truck sold recently that could provide comps to share? Searching online i don't find alot. I find high priced fancy ones or a couple basic ones. Mine is a 1957 painted but horribly peeling now sadly. And it's not original. Has a 90s engine and transmission in it. Mustang ii suspension., plywood bed etc But she looks amazing from about 40 ft back haha. Anyways. I sure hope you are all doing well. I haven't been on in awhile since I haven't had the money or time to work on her. Any ideas would be greatly appreciated. I dont have 50k to buy her out of the marriage if they order that and I would be beyond devastated to lose her. Thank again for any thoughts
