what are your plans after you get a truck. drive the crap out of it or leave it parked afraid it will lose value if you drive it? personally without seeing either one i wouldnt pay for something that high and able to spot what the high price tag was based upon. for that price id be wanting to smell fresh paint on both of them, new rubber, engine rebuild new brake system,new steering componets. you change the 50 back to 6 volt and there you have your close to stock your looking for. why would you want to go from a 54 or later 235(im going to assume upgraded during frame off) to a 216 just because of originality? as for a five window i dont know what all the hype is all about in value since i dont own any. i think its for people that cant read mirrors while backing up. buy the one your gut tells you to buy. if you cant make up your mind flip a coin. is seems to me money isnt an issue on your end.
