question on the Caltracs

I got a setup of Caltrac 4200 Drag 2 hole profile setup.

I noticed the spring plate does not come with a shock mounting stud.

What would you recommend? This is for a 67 Barracuda

OH, that sucks.
From doing an image search for those I see people added a plate with the stud on it like mancini sells, so it looks like some investigation on that part or some fab is coming.
