Can some verify that a 68 4 door cutlass decklid is the same as coupe decklid or is it common to the convertible for the 68 model year?
thank you

 

Confirmed - I've sourced one from a 4 door and fit perfectly on convertible.

 

Ok, so 4 door and convertible are the same and hardtop/coupe are a stand alone..
thank you very much for the quick response.

 

The easy way to tell is to look at the upper corners. Square corners = coupe. Rounded corners = convertible or more-door. This is why you see more "convertible" trunk lids for sale than there were convertibles made by Olds. Also note that the convertible trunklid is overall narrower than the one on the coupe. Note where the lower corners of the trunklids fall in relation to the tail lights.

 

Good comparison, thank you Joe.
