Early 8-1/4" R&P pumpkin from an auto

Looking for an 8-1/4" rear axle pumpkin assembly out of an early 6 cylinder axle. This is not like the common 8-1/4" rear with the rear cover but has a carrier very much like an 8-3/4" rear axle. These early 8-1/4" rear gear sets showed up in 62-65 B-bodies with /6's and maybe other. Wanting to get the complete pumpkin for a /6 auto trans car with the 2.93 ratio. Please PM here; thanks!
