Yes, the walls are thick enough to make the groove. When removing the caps, you could use the cap slam method, but it’s easier to just take something sharp, get it under the cap and then pr it out. If that doesn’t work out for you, then use the cap slam technique. ---

When he says slam he means it. You don’t just push the axle through or you will break the cap. If you slam it, it will pop right out. If you decide to pry it out you will have a mark where you dug the tool in. Either way works though. I just slam em. I do at least 40 or so a year and haven’t broke one yet. ---

When you get a FHZ, I don’t think you get a free bearing. Spacers are a standard when you purchase a Duncan(unless the yo-yo doesn’t even use a spacer). ---

I’m sorry I forgot about that part of the question. Yes when you buy an Duncan that uses FHZ type spacers then you get an extra pair free with it. Its their way to widen the gap. ---
