14x5.5J 822 1966 dart sbp wheels

These wheels are off my 66 dart gt and I'm fairly sure they are the original wheels. According to the stamp they are made in the USA by Electrofuse but are not date coded (that I can find). They use the larger 10 1/4 OD dogdish type hub caps. All of the wheels are in excellent condition without pitting.

Does anyone out there know about 66 sbp 14X5.5J 822 wheels. I thought that they were kelsey-hayes made wheels used on 340 darts and dusters.
