48 Dodge truck restore

We recently bought a 48 Pilothouse B3,my 14 year old daughter and I are planning on restoring it to close to original as we can. She would love to make it her first vehicle? It seems that part for this vintage are hard to find? My plan is to take it down to the frame media blast and bring it back up. I'm looking for all the help I can, I'm a first time restorer.
