Which crown race for new fork and bearings?

Hello, I recently got my hands on a used 2010 Trek Madone 4.7 frame. I'm trying to gather the headset parts but I'm a little confused about trying to find a correct crown race. I don't have the matching Trek fork so I'm using a new fork that has a 1.5 taper.

The bearing I will use has these dimensions: OD:51 x ID:40 x H:6.5 x A:36/36°

Can someone point me to the right direction?

Thanks in advance.
