To Sell Or Not To Sell...Mopar Madness

You could make a few changes to make it more appealing, will give you a better chance to find that buyer that wants a fun driver.

• Switch to the oem front seats like you mentioned.
  
• Find a Dart/Valiant parts car and raid it for all your missing parts. Try to buy a rusted out POS so you can buy it cheap then crush it and recoup your investment.
  
• A bodys already have a wider front track that looks a bit awkward with certain wheels, switch to narrow fronts and fatter rears. If you don't want that look, at least find wheels with a deeper backspace so they get sucked in more.
  
• Do some budget paint, but take tons of pics of the body beforehand to show how solid it is. Since you're changing seat colors, body color is more flexible. Maybe do a poll here and see what fellow A-body guys think it should be to look the best.
  
• Dress up the grill and maybe the rear trim with some masking and black paint. Not totally blacked out, just parts that give a nice contrast. Example below.
