72 Scamp and 440

Also im going to pick up the car this weekend. The guy told me theres a 73 duster next to it if I wanted it or I could have any parts off it I needed. I only have 1 trailer and its a 7hr drive. So can you think of any peices i might want to grab off that duster that would help with conversion. Or peices I might be be able to make some cash on to fund my project.
