don't take any of this as being pricky....but....
it really does sound like you created this thread for opinions and your not liking the opinions your getting.....it sounds like you have already made up your mind .....and trust me ....I have got on the 1 track mind set before because I WANTED a car bad enough......then once I got it.....everyone said " I told you so " and ended up being a money pit and a huge mistake.
don't make that mistake!
you may be bored of your truck,you may be thinking its summer and you want an old mopar to cruise in or whatever the case......but don't pressure youreself into the trade.
you say your trucks fenders have rust....no big deal....but new fenders for cheap and swap them on in a matter of hours.
the dart has obvious rust in the quarters and there WILL be more hiding.....and thats not a cheap OR fast job to replace those panels.....not sure if you have checked to see what those body panels run for or not?......but not cheap!.....then you have to take into consideration its not a simple nut and bolt swap.....your looking at cutting and welding in new.
and while your in there I am sure you would probably find the trunk extensions are rotted also and the rust may have extended to the trunk floor and wheel houses.
the damage is not going to be as a simple fix as you may think....the hood is sprung,the fenders are dented,it looks like the fenders got into the doors,all the notable front end parts broken,the framing is tweaked...and as mentioned before its a Unibody car.....its not going to be right no matter what you do.
here is an example of what even minor stress to the chassis of these cars can do......I have a 72 plymouth duster, the previous owner had a pumped up 360 in it,no subframe connecters ,took the car to the track and pulled the front wheels coming off the line, just that alone managed to put an outward facing crease in the drivers side quarter panel!.
not to mention what smoking a ditch would do to one of these cars.
and on top of it the interior isnt exactly perfect.
I think you should listen to everyone and do the smart thing and back out of the deal while you have the chance.
take and get some fenders for your truck, throw a quick paint job on it and turn around and trade it for a done running and driving clean mopar!!!! ....them trucks are cool looking trucks ( my buddy has one he built and has about 24" of lift on it with 55" tires I think it is.)
sorry for the long message...just trying to point out a few things to maybe help you out.
think it through real well so you don't make a mistake.
