MOTM

I'm gonna buy a couple of dotcom Q111 panners.  I've long lusted for an MOTM panner but now I can't wait anymore.  

Can anyone tell me what mounting problems I'll need to overcome to mount them in 19A rails?

From what I could research, I might have to enlarge the Q111 #6 screw holes to accomodate the 19A #8 screws.  My doubt comes from the possibility of a vertical hole misalignment after enlarging the holes.

I can live with the horizontal wasted space.

Has anyone ever tried mounting dotcom modules in 19A rails?

Thanks, John Speth
