Thanks again Mark

1/2 Shafts--The small blocks and the first 100 or so of the 427's used a smaller u-joint. I think they used the 1350, but I would have to check. I can do that tomorrow. I'll have to brush up on my Polish to read the drawings

Knock offs--forged aluminum. Probably something like 6061 T-6.

Front hub--forged from a minimally alloyed steel--probably 1040.

Rear hubs--forged from EN40B steel. Similar to 4340. Fabulous alloy for strength, but horrible corrosion resistance.

Front upright--forged steel. Probably a steel with minimal alloying. We make them from something like 5140.

Rear upright--cast steel.
