Ok, call me stupid but I really don't know how to differentiate between an E-body and B-body K Frame. I have looked for a part number on 2 I have but can not find them anywhere. Is there a specific place to find the part number on these? I just don't want to accidentily install the wrong one and have any problems. Thanks in advance!

When I die I want to go like my Grandfather did, quietly in his sleep. Not screaming like the passengers in his car.
