Well,
Never be afraid to learn something new, although some lessons are painful. You might take this opportunity to get some dollies and a body hammer or two and try your hand at straightening out that fender. It may never be showroom quality, and ultimately you might trash it for a better one, but I guarantee that you will get respect for trying.
I have soldered up many radiators, and you might try your hand at that too. Again, it might not be pretty, but you gain a skill and can get 'er back on the road.
The cowl damage may require professional help.
Still a great truck, and now that you have dinged it,it really is your own. Don't even think about getting rid of it. The bolters here will lend a hand.
