1964 Pontiac Bonneville Rear Suspension Upper & Lower Control Arms Coming Off For Rebuild.

One of the lower control arms is crushed in so I am going to remove all 4, and the springs, for total going over including steel reinforcements weld in. Can't get the 8 bushings so I am going to use the pour in urethane stuff using 80A. This will be a long process but needs to be done.
