Kevin, your link does not include 1937 door handles, which are different than the later models. The spring in the '37 is a coil spring inside the latch body. To disassemble requires bending tabs to separate the mechanism and the drooping on my passenger side is not bad enough to risk the damage I might cause. I think Jerry may be correct that the droop may be due to wear on the mechanism that could be corrected with judicious welding.
