I don't recall what year Willys motor co. became Kaiser Willys and then when they again changed to Kaiser Jeep. That one there is a 1955 to 1967 and probably NOT the later 68-71 of the Kaiser era. Kaiser bought Willys-Overland in 51 and changed the name to Willys Motor Co., then Kaiser Willys Co., then Kaiser Jeep Co. The steering column/wheel is Pontiac and is a modification. The Stock motor will be either a F-134 inline 4 cyl Hurricane or a Buick odd fire V6 dauntless. If it came with a 6 it is mid 60 era. NICE JEEP!!!
