New Mopar "Convert"

Hey guys, new to the Mopar scene, have always been a (shhh) chevy guy but now looking to 'convert' to Mopar.
Looking at a 73 Plymouth Scamp in the morning. Asking price is $300, engine/slant6 nonrunning, everything else is 'complete' (to be seen), and it has no paperwork.
Is this a good deal? The main concern I have is the lack of paperwork/bill of sale only.
Any thoughts or suggestions would be greatly appreciated.
