Can you provide me with the dimensions of the bolt? And, do you sell the bolt only? If not, where could I purchase the bolt?

Screw is M6, it’s widely available on Amazon as the “top cap bolt”. Also is in “top cap and flower nut kit. “ you’re better off though going to hardware store for a steel M6 screw. 3” long should be fine.

This is for a tapered or straight headset?

It's for a tapered headset as shown in the picture if you scroll down and view the item details before purchasing.
