I just installed 2 Hella Supertone horns. They are Hella Loud. They will produce a ringing in your ears. I'm not a fan of the actual tones though but I don't use the horn much anyway; but when I do it means EMERGENCY! so I wanted loudness. Anyway, I thougt I'd share a couple things I found out (I will add pictures later). I installed from below and found two bolts about 5 inces horizontally apart from each other above the stock horn bracket. I found a 'T' bracket from Home Depot that has holes in the same spot so I thought I'd use that. The 'T' bracket also has a hole near the bottom of the 'T' that the two Hella Supertone horns can be attached to.
Also, I noticed there are two bolts below the stock bracket down the center of the radiator bracket. Home Depot has a 5/16 coupler bolt (looks like a very tall bolt) that will screw onto the exposed threads so that you can then screw a bracket on to that bolt and again be dead center of the car instead of off to the side (I'm anal about wanting things to be balanced like that).
Anyway, I thought someone might be able to use that info for their install as I did mine.
