Here is a pic of my radiator clearance.
Filter clearance. Will be fine.
So afaik as long as the hood has the same bulge starting at the same spot as the stock hood I will be fine. Now it's a question of which cowl hoods have the bulge that begin at the same spot. I also want a high quality one as I live in Australia and can not afford to be buying a poorly fitted one which I have to return or whatever.
Georgia Flash 75V8 has the following one and I've sent him a pm asking him about it. Not sure where he got it from but it looks to be fine.
The Reaction Research one looks fine as well but not sure about clearances there. I have not used the JTR mounting kit and my radiator is as low as it will go so I have to forget that idea and find a hood that has similar clearance at the front to the stock ones.
cheers
