According to Legendary the frames are the same for 66/67 A AND B Bodies. The foam is even the same. I compared the seat tracks of a set of 67 B Body seats I have with the 66 A Body seats going in my 65 wagon and they even look and mount same. The upholstery is of course different between 66/67 years and A/B Bodies. Hopefully this will give you a wider audience of potential buyers.
