I kinda figured you knew about the difference. I had forgotten that the lip was different too.
And I noticed some do polish better, but didn't have enough wheels to correlate that to a wheel type, I figured I was just getting tired of polishing!
Yes, I would agree that the flat type is forged, and the one with extra material to reinforce it is possibly cast. Casting would be cheaper, so would make sense for later-years cost-cutting. But casting can so easily have internal voids and occlusions, whereas forging doesn't, so a cast wheel sounds kinda risky to me, so I would almost bet that both are forged. But then it wouldn't make sense to develop a whole new tool to forge the same wheel. Actually, the more I think about it, I realize that I know a lot about different things, but I also know I have no idea what the factory engineers were up to in the early 80s.
