A-body 8-3/4 drums

My friend sold his 69 Cuda this past weekend and the buyer was saying the drums I had were not right. Got me second guessing myself so I’m inquiring on here. My understanding was ALL 8-3/4 drums were made with the wing-flange, fronts didn’t have that piece. Even the 7-1/4 had them only smaller. Am I right?
My 68 340 GTS auto had them (bought in 1970)
All were not made with the wing. My 69 and 70 Darts both are 10" and no wing. Actually, I only seen a few with them. Might be a northern thing as some said here. I'm in South Florida.
