I have a 70 estate wagon and would like to get the following: Front Disc brake set up Front and Rear sway bars(biggest I can get) and air bags for the rear to help me tow. New rear heavy duty springs My dad had all of these on our 70 wagon when we were kids but for the air bags he had air shocks. I have those and would also like the air bags. Any info on this stuff would greatly help me out. I have big plan for this car and have no plans on going to a truck for my tow rig. Thanks Doug
