well i decide to fit the thing today. the main problem was turn signal fitment. i got it all straightened out after some trimming. as far as the 2/3 rule for air incomin to ic, it should be good. about %70 of the ic is exposed and a bit covered by foglight and turn signal. so it as close to 2/3 as i can get.
before anyone mentions about my paint, i already know. it will be going into paint booth as soon as i get a beater.
