Thank You for doing the research to find that handle.
I too ordered a replacement handle from one of the 2 major parts suppliers. Though their handle will fit the door it is tighter to use since it's rectangular. The handle you found is contoured for your hand and is more close
to the original handle shape. It is solid and heavily chrome plated. This handle should easily out live the originals
used, as they were hollow.
The link in the original message, is no longer valid.
Here is a place you can purchase this superior handle from.
