I was out testing what the lights look like from where. For the front, I think I've decided on two under the canopy in each corner, facing forward with a bit of down angle. For the lowers, will mount in same holes as original ones but the led pods are lower profile (equals more useless) so instead I slid them to the side of their brackets and angled them out to the side about 45°. This allows for top lights to be both pointed forward while still lighting up the whole field of view.
For the rears, I ran into a little snag. I never realized in the back-top of the cage there is a piece of square tubing. I could get a longer bolt and go through it but like Ford was suggesting, maybe that's not an ideal place.
I might do the duals up top angled out at 30°. The lights are 60° so that should get me 120° in back. That will cover 45° of articulation with 15° to spare.
