I hate to say this but it is very hard to value at this point. I suspect that most don't want to piss you off with a low ball number. In reference to your question, I think it is probably worth $10K to the right person, the challenge is finding that person. The fear most will have is whether or not there is any damage to the drive train, the body damage is evident for the most part and if the drive train survived undamaged it would be a deal as there is more than $10K worth of parts there for sure, however if the drive train is wounded it changes the equation to a potential buyer. I am not saying it isn't worth it, just that the feeling for a buyer is that they are getting used parts and as such there is always an air of mystery and a gamble.
Not all trying to get you to lower your price, just putting this out there. Key here is finding the right person who needs what you have, has money available to buy it and time available (or anticipated) to devote to it (whether repairing or parting out). If there was someone who has a relatively clean project car, this would be an awesome swap and they would be money ahead not to mention selling off any parts they are not going to use.
