Theses are the lightest springs made by Caltrac for this setup. And I would have to move the pin to bring the axle back. The rear glass is out but other than the seats the body is bare.
I think this is about 1000 pounds light at this time. without the front and rear glass, no engine or transmission, hood and fenders. ANd after looking at a od photo of my coronet in the same condition, it is riding the same way
