Thants the reason for doing a mod to this (if body mounts wont fit in width, it sure wont be aligned front to back.. but it is pretty close what i can see on pictures), it should not be to hard.. but i have to see it first in real life and then decide if it's worth modding or just making another hole in the body, hopefully i wont have to do any more holes. I have ordered those body mounts anyways, so i hope i can use them and solve it that way.

If i decide to make some holes.. it's not easy to put it down perfect the first time, i would first place it in perfect position and then try to use a lightsource from below and mark it from above, if not there is always the way to measure... but that takes longer time and you have to do many measurement to rule out any faults, it does takes time and patience but will be totally perfect in the end if done right.
