OK, so a regular Colonnade coupe (LeMans, Century, Chevelle, Cutlass S) with the semi fastback roof has a 112" wheelbase. The formal roof coupe (Grand Prix, Regal, Monte and Cutlass Supreme) has the same wheelbase as the sedan, 116".
My question is, where does the extra four inches go?

My first wild guess would be rear seat legroom
Second wilder guess - longer hood?
My info says 112 for 2 door 116 for 4 door 73-77 where did you get your info?
Looks like I am wrong folks, I hang my head in shame! I guess all two door Colonnades are 112" WB. For some reason I had it in my mind that the GP/Monte/Regal/Supreme were on the longer 116" WB. Sorry about that!
