No, the front end chrome differs between the HJ and the big Kaisers. The parts in question do not interchange.
In an earlier post, someone asked if the windows were coated. I'm not sure of the pictured cars, but I know a fellow who had to hide 3 Kaisers from nosy neighbors so he painted them with brown house paint. The chrome, windows, sheet metal and even the tires were all painted brown. I guess that worked as the neighbors didn't bother him after that. One thing to note, the thick house paint actually protected the exterior of the cars. Scraping off the paint revealed decent chrome.
