ballast

anyone have a good suggestion on where to put it? i got one coming and can't figure out where to hid the thing. Thanks, Sid

Hi guys, I wanted to know where should I install the ballast ? It's not a slim one. I tried the air scope, but it looks impossible. Since I have a small headlight cowl, I just put it for the meantime behind the speedometer. But I would prefer to hide it, to avoid anybody to get a free ballast...
