1973 GMC Jimmy How Rare Whats It Worth

[NorCalCruiser]

I am looking to pick up a new project and found this for sale. I have never had a Jimmy and cant find much information on them. The owner says it is all original and from the pictures it is believable (I have not been able to look at it in person yet). So anyway does anyone know where I can find information on this truck? What are the production Numbers? Whats it worth? How desirable art the Jimmy's over a blazer? I have been looking for a new project and if this is worth it I might restore it back to stock condition. Does anyone know what color this is, i found a paint chart for this year but cant tell if it is Ochre or Yellow gold.
