I have had what appeared to me as a 70-71 Hemi K frame. I've owned it for somewhere between 22-25 years. There is no obvious signs of repairs or replacement pieces. I tried to swap it for a 66-67 Hemi K frame a month or so ago and was told that it had changes they were not interested in swapping. Someone please tell me exactly what I have and about any modifications or changes they see on this item. Also if anyone has a 66-67 Hemi K frame they would be willing to swap for this one. I've been told so far that it's a E body K frame with early B body modifications.
