Thank you for the compliments gents.
Greg, that's correct, I'm using the hood latch bolt and the original horn bolt to attach the corner braces for my mount. There isn't room for the Hellas anymore, at least at that location.
I'm looking into mounting the hellas off the radiator support bolts at the moment, trying to get the angle correct. The problem with the Hella 500's is that they're freakin' huge, so I don't have exactly a lot of grill space to work with. Not to mention I'm a bit iffy about blocking off TOO much airflow. The added "coverage" of the lights is offset by the more free flowing grill since I took off the mustache, but if I add the horns back in the upper grill area, I'd be blocking maybe 80%+ of the air?
