78 CJ5 Fiberglass body firewall help needed

[Harleyyoung7]

So I am starting a new build on a 78 CJ5 with a 79 motor. It has a fiberglass body and not a single piece of wiring on this entire ride. My first step after taking the motor back out is to make the holes in the firewall. As this is my first jeep and my first complete build by myself. I am wondering if you can assist me with measurements or a template for this firewall cutting? I would really prefer not to mess this up as I do not have the money for a new tub in fiberglass or steel. I Have pictures of all the holes and what they are for as I have spent hours researching on these forums. But just looking at pictures is not really the way i want to go about doing this. I honestly would prefer a template if possible or at least all the measurements. Also with it being a 79 v6 motor is that really going to effect the placements of the holes? :ty:
