My trucks wont fit on my long board deck?

so i built a longboard deck from scratch a couple years ago and when i drilled the holes, the stencil had two different sizes and i used the longer size. i have some indi trucks that fit my sector 9 longboard but the holes for the Independent trucks don't match up right with the deck i built. does anyone know where i can find different sized base plates so that it will fit? and the base plate doesn't need to be wider, but longer. thanks in advance for your help
