64-66 cuda fold down seat into 63-66 dart

If you have time, please do. I have read that they are slightly different, but I can’t imagine why … but if they are, I can’t image by much. I am guessing the Barracuda seat bottom might be lower (shorter springs or reduced padding) so the seat back could fold down into less space to make the rear floor flat, but I am thinking the width is probably the same? Totally guessing but it would be great if they were interchangeable!

Sorry, got bogged down in other stuff and forgot to measure. Looks like both seats (63 Valiant convertible and 65 Barracuda) are 45 inches wide. Didn't measure depth. Here are pix of each:
