Not sure we need to discuss pricing here...?

Generally.
Look at what new parts cost and adjust for condition, not available new so look at new smaller truck bed prices and extrapolate.
Also look at sold items on eBay.

Then location can affect pricing particularly for hard to ship items.

The appropriate section for parts for sale is the swap meet when your ready.
