Since Kerry is all set up I think he should do one for each of us! I picked up a repro hub unit, no reason. I didn't need one, or want one, and it's not better than what I have, it's just what I do! Anyway, can't comment on how solid it is compared to GM, or spline quality etc but the pebbled effect is very fine, almost non-existent, like 180 sandpaper and finer than Brian's version above, and still had to paint it a better shade of satin black. I also suspected it may be a lighter weight casting, or thinner side walls as where it has been clamped during machining has flattened areas. There's 6 cast braces inside for strength but this particular unit was clamped across the hollow section, poor workmanship. Others are probably fine, even with slightly thinner wall. I've only compared from photos as only GM unit I have is installed. So I'd say if ever needed that redoing an original is a worthwhile little project. I'll keep en eye out for another one, just because.
Also, wheel came out nicely Brian. I think it looks better than the attempt on PY a few days ago. It's also good, especially since just old wheels clean-up, very good, but I like the slight contrast between the black vinyl grip and the blackened spokes. His looked like it had been done in the same shade all over, there was so little variation and too much sheen.
