I need to buy a new top cap for the build I am making but I have realised that the fork threads are not the same as my new bmx with odyssey r32s.
The fork is from a premium bike and is abit old but I am restoring it and need a new top cap.
Which one do I need.
Thanks!

Any standard top cap and m6 bolt will do. Dont need anything special like the bmx ones you’ve posted. The last slide should do. Or go to a bike shop, they likely have dozens in the parts bin for really cheap
This looks like an old star nut. Before we had threaded steerer tubes you had to cut the tube to the length you want and hammer in a star nut.
The diameter for those are usually M6 x 35 mm
Yeah it looks like a old style one with a 6mm bolt but if you buy a replacement I’d swap out the star nut and use the one that comes with the new top cap set
