Yes, 67's are different from 68 and 69. Yes verts are different all together...however I have no experience with the verts. I know Frank(Prodigy Customs) is doing a vert.
I did a 67 Coupe and the frame rails are very different. My close out was larger to cover the open space in the DSE well. Shoot me some pictures and we will see if we can help you. You can see some close out pictures on Mikes homepage.
