69 Chevelle headlight buckets

[bluel78]

Does anyone know the correct sequence and letters used for installing headlight buckets for a 69 Chevelle? Read conflicting answers on the Chevelle site and none of the answers match the assembly manual. The Chevelle site comes down to two ideas. Starting from the drivers side ABDC. If I try that the passenger side ends up with the headlights sideways. The next idea is ABBA. This would work but doubt it's correct either because it doesn't follow the assembly manual. The manual has part numbers for the assembly so that would include: headlight, ring, screws and the bucket. The inner assembly left and right are the same so those could be B. The outer left and right assemblies have a different number so they probably aren't both A. If they aren't in the correct order they won't be centered in the headlight bezel. If anyone needs help turning a five minute project into a multi day event let me know.
