Aligning 3D objects in NL Editor

I slightly altered to standard LSM object in order to fit with my ride that I am doing. My launch areas are both angled slighty up (just like the real Intamin accelerators) and the second one is on an angle in the editor (on a diagonal).

My issue is that when I place the LSM Module to put on the track, I can't line them up perfectly, so when I put them in the track, either part of it dips below the rails or juts out above them at one end. Also I can't run the Module completely parallel to the track, so it is sort of cockeyed.

I have to snap set to the bare minimum, so I'm at a loss as to what to do. Any ideas/tips on what to do next? Or will I just have to do my best and accept that I can't rotate/tilt the object exactly right?

Thanks!

I don't know if this can help, but there's a button to fully disable snap: "Snp"
