I've had the wrong impression for many years. Our Cutlass had coils, but that was 1979. This has been an educational discussion!
Although four-links with angled upper arms are not the best for axle
control (ask early Fox-chassis Mustang owners about wheel hop), they must be better than leaf springs, and with good bushings they should work well to manage an attached trailer. If there's nothing in the rear coils (such as a concentric shock) air bags such as Firestone Coil-Rite or Airlift 1000 can be easily added to adjust for trailer tongue weight
... a nice feature.
I have some Air Shocks on there now. They are old and need replaced but would think that just a new pair of air shocks should do the trick. I am glad everybody is enjoying my blog. Nice to see some trailer freaks and Gear Heads too!
