What exactly is the difference between a 70 b-body steering column and a different year column, other than the lockout? Would they be interchangeable? It seems that the 70 columns are extremely hard to find. If anyone has a picture of a 70 b body steering column, (the lower half, i need to know where the bearing goes in relation to the shift tube). Im not even sure i have a b body column as of now (my car was built by idiots)
