Need help mounting A/F gauge..

Hey guys,
I'm trying to figure out a way to mount my a/f gauge. My wife bought me a new gauge with a carbon fiber cup, just like the boost gauge that I have. Right now I have the boost gauge mounted on the side of the riser closest to me when i'm on the sled. It's in a great spot.

Now my question is, where can I mount this gauge so it is in a handy spot to see, and so I can still use my new cup?? If I were to mount it on the side of the riser kind of tilted toward myself would this jeapordize the integrity of the riser?? If not, I will mount it there, but does anybody else have any input??

Thanks guys.

I guess what I really need to know is, will drilling 2 small bolt holes in the side of the riser weaken it too much?? That way I can have both close to eachother and it will look good at the same time.
