I do not know specifics about this Road Runner. But looking at the photos I can tell you a couple of things that come to mind:
Hood Pins were never an option on the 1969 Road Runner. Dodge did offer them on 4/7/69 - Chrome hood hold-down pins (code J45) were released for Super Bee, Coronet R/T, and Charger R/T. Hood hinges and front latch were retained.
It looks like the Chrome Exhaust Tips are from the Super Bee/Coronet R/T which are square while the Road Runner 's are more oval in shape:
Fixing the Exhaust Tips is simple. Fixing the Hood Pins if your friend wants the car to be "factory correct" is another story - as far as cost
It appears to be an A34: Super Track Pak which included the Dana 60 with 4.10 gears, sure grip (posi), 7 blade torque drive fan, 26" high performance radiator with shroud and power front disc brakes.
