Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

Just don’t put any MoPar, Chrysler or Chrysler corp. part number symbol or logo on the part your copying and you can go to town.

Once you put one of the above on the part, you could be in big trouble.

If a little guy to a big corp makes a tail light from a basic, ugly poor quality copy or just a simple part that looks similar to an exquisite reproduction, as long as the part is devoid of the above, there good to go and sell without repercussions.

They have to do this, because if they don't they could lose their trademark protection. They have to pursue all instances of unauthorized use of trademarks, or they could be told down the road "since XYZ company used the pentastar on their parts and you knew about it and didn't demand they license them and didn't try to stop it you can no longer claim exclusive use of it." That happens so it's not surprising that Chrysler enforces trademark infringement. But sometimes their tactics seem very heavy handed. Maybe those folks deserve it for ignoring previous warnings, I don't know.
