Question on parts value

I would appreciate some thoughts on pricing or value of the parts and why there does not seem to be any interest. What am I missing?
There are some strict rules on the forum that make it hard to just ask the members what a fair value is for something that you want to sell. I understand the reasons for them but the situation isn't ideal.
The absolute ONLY thing good about the Moparts site is their sub forum of WIW topics. What's It Worth. That forum is specifically for people to ask a value of something that they are selling or to assess the value of something that someone else has for sale. For that site, it works. I would LOVE to see something like that here and at FBBO.
I hate to over-price something and look like a delusional greedy jerk but I also don't like the idea of selling stuff too cheap where the buyer then relists it for double and sells it.
