67-68 Cuda trunk lid differances

The outer shells are basically the same. I have a NOS '68-'69 without any trim holes. If ya look at the crash sheets from back then, you got a certain amount of time to drill the trim holes!
The inner skin/frames are different '67 to '68/'69. The '67 in between the bent reinforcement/say frame there is only 1 layer of metal which is the outer skin. On '68/'69 the entire lid is 2 solid layers of metal. I have some examples if ya need pics. Or you can post pics of yours.
Also the inner frames have different access cutouts and holes to access the nuts for trim clips. A '67 is a lot different than a '68/'69 on the underside but the exterior metal will work for any '67-'69.
