1998 Grand Marquis A/C capacity

It looks like the label is supposed to be on the evaporator case, but it's gone. Can anybody help me with the charge capacity? I've searched this forum, and the entire internet from start to finish, with no success. Thank you very much.

According to this Motorcraft chart its 38 ounces of R-134a refrigerant.
