I need a little help. I just purchased my first bronco(1969) and currently have engine out. I recently purchased a new wiring harness because wires were jumbled and frayed. The bronco has an auto transmission but no disc brake or power steering. I had planned to add these two features later but should i bite the bullet now while the engine is out? What is the least expensive way to convert both of these items? What will i need? Any help would be deeply appreciated.
