    So I’m trying to put together my ‘57-‘59 Hawthorne frame. There was one cup in the frame when I receive it but I need to buy a whole headset or just a new cups that fit in the head tube. I had two on hand which didn’t fit. I’m having trouble finding the correct headset or even just the right cups. I’ll be running a 1” threaded BMX fork.
    I’ve added some pictures of the chrome cup that was in the frame when I received it.
    The outside where the bearing sits is 43.5 mm and the part that goes into the frame is 33 mm.

    The black cup is a regular 1” BMX threaded headset but it’s too loose in the head tube.

    Any help would be greatly appreciated!
    The only cups I found that may work are below. Would they work with a 1” for though?

    Thanks for the info! I thought about just shimming the black 32.5mm cup to make snug to fit the 33mm headset but I wasn’t sure what to use.
