need help with p2k gp60 details

bought my first new loco, a p2k gp60. The a/c unit that goes on the cab roof has 2 small nubs obviously to fit into locator holes on the cab roof. The cab roof has no pre-drilled holes, or even dimples to use as guides to drill my own holes. Should I just trim off the nubs and glue? Also the instructions only show an exploded view of the loco, and nothing shows the exact location of the a/c unit. Is it centered on the roof or off to one side or what? Sorry for the seemingly dumb question, but I am pretty new to this. I may just have to find some photos on the net to find out the location. Many thanks!

Hi there, I know in the past all of my locos have came with a flat pice of plastic that has holes in it. I don’t know about the gp60 but on other P2Ks they have supplied it. your directions should say on what way it goes on or the plastic piece will have guides. Hope that works for ya.
