Was just trying to install my new Demco Base Plate on my 2005 KJ. The holes are not lining up from side to side. End to end of the holes on the plate is 31" and on my frame the holes are about 30 7/8". I can get them in but they're on a angle and I'm not comfortable with that. Theres nothing in the instructions saying to drill the holes out, besides the back ones. I'm thinking thats what I have to do. I did notice they drilled the holes out on the roadmaster install. Any advice, please?
