Looking for help installing #905's on a Atlas shay, first run. Everything I see say easy install. Remove original install #905. Not on mine. Atlas screw is to large for hole in 905. Hole in frame is to far back to accept 905. New hole would be in seam between frame weight and plastic body of the loco. Could use some help.
