518 vs 45RFE

Sorry I was not more clear. (better english??)

Does anyone have experience with putting the 518 in an A body that can tell me how much cutting is required?

The Info I have seems to indicate the 518 will fit with no mods to the hump. I was looking for hands on experience. I looked at the major cutting in the pictures and got a little nervous.

Thanks,
