Shapeoko 3 assembly Dewalt router install

Total noob here…I put together my Shapeoko 3 today (and yesterday). I ran the hello world with my sharpie and it went great, makes you smile seeing it move for the fist time. My problem is trying to install the dewalt router, the router holder is VERY tight and i cant get it in even close to what the instructions say. Is there a trick?Any help appreciated.

Use a screwdriver or small pry bar to pry open the mount to insert the router.

Thanks, I am gonna have another go at it soon and will try that, I tried prying earlier but I will be more aggressive now.

a bigger pry bar worked!!
