I've got numbers for 3 different stabilizers. The Moog is SSD13 for the base Trail Boss, SSD81 for the Super Trail Boss. Should be able to get that one at any parts store that carries Moog. The other one I've got numbers for is the Rancho, which is RS97355. That one is also available through Sears, part number 14353. The part numbers I've listed are all for complete kits with the mounting hardware.
