When I was younger, my uncle and I repaired a bike just like this. The seats were missing, along with a few vital parts and I thought it was a really fun project! It would be fun to do another project like that with my son. Where did you find this bike at? I think I may just go down to a junk yard to find a bike that we can restore, along with some parts that we could maybe use. http://www.sherwoodmotorcycle.com/service.html
