a guy i know just put b body headers on an abody and they fit but they did require some dimpling you can only run manual steering he had to dimple around the steering column (its a column shift auto) needed to dimple a few other places as well they work but do need to be "adjusted" to fit without rubbing but big block a body headers are spendy so if your short on money but have some time it may be worth a shot also ive heard not all b body headers fit only some but i dont know what brands or if that is even true good luck Justin
