I priced replacements at around 75 a pop. Its almost cheaper to buy a whole set, and FWIW you can get a set of 8 from a mustang for 200 or so, and have 2 left over! You might check E-Bay for some 19lb Mustang 5.0 units, Ive seen a few sets on ebay go cheaper than a single new one, and you have 8 to go through if they arent in the best shape.
