Huh, weird they dont have the kamanari 3 port listed anymore.
Anyways, I was/am running that airdam on my 75, however the airdam is the 240 issue with the lower turnsignals. It required some triming around the grill opening but it was no big deal. That is the only experience I have to offer. Dont know about the stock parts or other aftermarket parts.
Super old picture....
