I've been following this car on Ebay and thought I would share it here since I won't buy it anyway. It says it has a 69 Camaro disc brake axle. I wrote to the guy and he said it is a BR code from what he can see. He sent a vague picture of the JL8 setup which I have attached. Seems like a cool car if the hood was changed.
