Good Morning, yes they are dual matics, strange they were only made 250 miles from here. Only the second set I've ever seen and that was of a pic on a LCF pole truck in Kansas. I've only had this B truck couple of months. You must be thinking of the 66 C80, I've had it 7 or 8 years, its got the big Warn hubs on it, they have the hole in the center for a grease zerk that screws into a 3inch nipple that screws into the stub axle to lube the knuckle. The smaller trucks with 6 hole buds do not have the hole in the center.
