Mike,
Yes, I can build you a three point- left or right or both or a full 4-point that goes from side to side. Their is no template as each bar is a little different. The bars are all made of 2" ODM roll bar material.
Putting them in after the body is done is no problem, just nerves and a litle time and caution.
I can make you a template to start with but you will need to finish it up with the roll bar(s) present.
They take the two inch bezels and gaskets (From Finishline) to finish them off.
Just tell me what type Drivers side 3-point, passanger side for 3-point or a full side to side four point. ALL bars fit under a top if you have one, in fact with a four-point you wont even need the top bows!
This is cpteddies 4-point:
