[Closed] Oversized headset cover...where can I get one?

Hi all

I'm doing a Cannondale hardtail hardtail build. The frame I built came with the bottom bearing and top cup already installed. All I need is a standard 1 1/8 bearing and the expansion ring which are easy and cheap to get.

The issue is that the headtube is 1.5 straight and needs 1.5 headset cover which reduces to 1 1/8. I can't find one for the life of me! Only other option is to buy a whole headset for 30 quid...when back in stock at Cannondale Spares in a months time! Seems a bit excessive for just a cover.

I think the headset cover is supposed to 58mm outer diameter. I reckon I may be able to get away with 50mm and up. A 1.5 to 1 1/18 reducer headset cover is what I'm after like this:

This is the actual headset from Cannondale:

Any help would be appreciated!
