A-body 8-3/4 drums

It seems the answers is all over the place (55 years a lot can happen) I’ve talked to guys who’s been around these cars all their life, one said Cuda had the bells and darts didn’t, generally, it depends on where each one was built, one said of all the 7-1/4 rears he had not one had the big drum (might have been offered very few bought).
Thanks for the discussion
Since the last A body Cuda was built in '69, it couldn't have factory "bell" drums that were only offered beginning in the '70 model year...
Factory 10 inch brakes on a 7 1/4 rear weren't totally uncommon, just optional. Had them on my '66 wagon, '68 GT and a '73 Dart 4 dr. Ordering front disc brakes would also automatically get you 10" rear drums, regardless of rear end size.
