When these parts are remade, may be a good idea to figure out how to redesign the inside for better distribution of air to both passenger and driver. Currently this is accomplished not very well with an internal baffle. Also, some of these units come with plastic louvers, some with metal--the metal ones hold up better. If the evaporator boxes are rebuilt, it might also be a good idea to use an oring type fitting on the high pressure side so there are no issues using it with the newer R134a refrigerants.
