Need help on mounting door handles

[jbgroby]

Any of the members have a door handle templet and/or can explain a simple way to use it in the correct manner. I used mine and drilled two small guide holes in my panel (the handle will cover those holes), but I can see where they will not line up with the base nuts. I had to measure these wrong. Any help appre. I've either cut the templet wrong or started with a bad measure and it went downhill from that point.
