1967 Chevelle SS396 Rear Axle Housing Stamp
Perhaps one of the most unique features of the Chevelle SS396 was its rear axle. It had an open-ended gear ratio which gave the car an impressive amount of performance, but it was also unique to this car. There is a stamp on the rear axle that will denote if the car is an authentic SS396. The code will read “KJ” and it will be one of the defining factors (via DIY Truck Build).
The axle housing and the design of the SS396 in general is what made the Chevelle one of the most popular muscle cars of all time. It was the interesting body styles that made the car resonate with just about every demographic. The car had a noteworthy appearance and nowadays it is one of the rarest and most expensive muscle cars on the road.
