what is the thickness difference in the body of a McCarty 594 SC and DC?

So I got 2 McCarty 594 SE now. well 3 but 2 are in the same finish that black gold thing. i noticed that the body of the SC is thicker than the DC. I search the net but can’t find the reason for it. all i see is that the mccarty is thicker than the regulars like your custom 24 or 22. However i fee like the SE DC mccarty version is the same thickness as the others. also maybe its just me and maybe pette from andertons on their video of reviewing the SE mccarty feels like the necks on the DC is bigger than the SCs…any opinions or knowledge to shed some light on this??
