As for 'other shocks', simply measure your stock coil-overs compressed & extended (remove the springs first), then look to Bilstein etc for a matching size. Besides Koni N.A. in Florence KY, there are a few Pantera shops that will rebuild or buy old Konis, notably Pat Mical (
www.patsauto.com) Most of the Vendors sell new replacement coil-overs of various brands as well, saving you the legwork to find one that fits & has correct damping for the fairly heavy Pantera.
