Please see picture 7 for the casting info of the rear end. It is alloy, as are the winters side bells. Please note the side bells have been modified to the studs on the center section. I am by no means a quick change expert, nor do I claim to be. Pictures titled "Rear Pieces" show the pile of innards that were also co-located with the housings. If you look at those and note piece(s) that you know specifically go with a particular center section, please feel free to reach out and let me know. This is one of 3 center sections being sold right now. Here are links to the other two: Frankland: https://www.jalopyjournal.com/forum/threads/frankland-quick-change-rear-end-w-tubes.1255415/ Unbranded: https://www.jalopyjournal.com/forum/threads/quick-change-center-section.1255417/
