I believe that the steering rack is the same as a Ferrari 308 with only a slight modification. The area where the 2 clamps bolts on has to be filed down a slight bit to match the old Pantera rack. The rest is identical. Tie rod ends even fit from your old tie rods. I installed these racks in both of my Panteras. No problems! And I believe that they're cheaper than a Pantera rack too. Usually a bunch on Ebay.
