[big gear head]

You are right Mitch, those are not the original 200 pound green springs. Those are the 800 pound springs used in the heavy duty Eaton and Moroso units. If it has the 16-10 gears then it's a COPO unit. If it has the 17-10 gears then it's a HD Eaton or Moroso. If it has 18 - 10 gears then it's a standard unit that has had the spring pack changed. Those 800 pound springs are a lot of fun to get in there!
