When you print the Ron Hopkinson rear bar template for the wheel-well holes at the correct scale (use the 4" line to confirm) on A4 paper you may find one edge clipped. Make sure this is the side with the taper and not the one that has to align with the corner of the wheel-well. There is one template for each side but you can print and use just one then turn it over and bend the 'Lay on boot floor' section the other way for the other corner:
