The bumper "2nd" set holes are always there. I have measured them and they appear to be 1/8" off (closer to the bed) when compared to the original hole placement, they do work though.

I haven't used the kit, but have shortened many frames, if your very precise with your measurements the rear cab mount should line right up....on my crew cab I couldn't precisely move the rear cab mount back since I used 2 frames...to locate the rear cab mount I loosely bolted the mount to the cab with the rubber mount in place then set the mount height in relation to the frame, clamped the mount to the frame and drilled through the mount into the frame to locate the holes.
