Take one in to Pep Boy's or NAPA and see if they can match it with a foreign car shock. I had a Holsclaw and as far as springs, I used the old ones. The spring perches were shot and rusted through so I made a couple of new ones out of stainless plate and tubing.
Do not be tempted to run without shocks---They limit the axle travel and keep the springs from flopping out.
