I'm doing a complete frame off restoration of my parents car that has never left my family. I have had all parts media blasted and primed and painted chassis black when appropriate. I am now trying to put together a rolling chassis. I have most of the original parts. I just want to put the essential parts back on the frame so I will have a rolling chassis so I can reassemble the car and see how everything lines up before I start any body work on the body or or any other parts. Can someone please tell me what parts such as upper and lower a-arms are essential to building a rolling chassis please? Thank you in advance.
