cost to re[lace rear air suspension with coil springs and shocks on 1992 Lincoln Town Car

I've decided to replace failed rear air suspension on our old Lincoln Town Car with coil springs and shocks I ordered from J C Whitney. Now I'm not sure about diong it myself and wonder what the labor should cost to have a shop with a good hoist do it.

Check the RepairPal estimator for your car--there should be Shock/Strut Replacement to give you an idea of how much labor is.

Most shops won't install a part that a customer brings in, however. It exposes to liability and warranty issues.
