Here is my blue 87, looks similar to your original, but does not have auto or power windows.

not $5,000, but I would be afraid what you will get in that range.

My '87 is listed for sale here. It's not a 79-83 and more than 10k, but it's a beautiful truck and everything has already been done to it.
