The item was originally designed for use on the 1947-50 model year Kaiser & 1947-51 Frazer. For the 1951-55 Kaisers, you have to work up a new contact point as the contours of the hood do not allow for install as shown on the box (where the installation instructions are found, there was no separate sheet). I know about the 51-55 Kaiser thing as I tried to put one on the 1951 Business Coupe when I had it.
