This is an eBay listing #271962397046. The listing has information leading you to the Classic American Iron forum; 'Saddlebags for 1946 Chief' in the Indian forum section. There is a lot of good information there and I have also posted a dimensional diagram of the aluminum adapter that is missing on the vast majority of the Post WWII Chiefs. Even if you are not interested in purchasing the items, you should book-mark the forum thread as this information is found no where else. Yellow53Chief 567ste.
