I need to fix the rear end sagging problem on my '85 Westy and need some
assistance.

Has anyone ever used those small "donuts" that are available from
various sources to all new life to old springs? I believe they are
installed at the bottom end of the existing coil to add lift. I don't
think this is a good solution but considering the price of coil springs
I feel I must ask the question.

It is my understanding that the rear springs in a Westy are different
than those in a standard Vanagon. Is this correct? If I end up replacing
the springs, would I be better off replacing all four coils or just the
rear?

Last question, does anyone know of a less expensive source that the
dealers for Westy/Vanagon coil springs? The dealer price is approx. $375
each!

TIA,
