Hello folks, I'm currently building up my new helius am and swapping kit over from my old ST. Whilst mounting the shock I saw that the the front mount is a bit wider than the ST.

They're both listed as being 16x8mm but I measure the AM gap as 18.5.

The mounts are obviously different design, and I'm wondering whether I should be spacing it out somehow, or just nipping it up. Can anyone help?
