One of the first things I have to do is repair the mods to the bonnet. Somebody cut the front of the bonnet and bent it up, they also put a very well made hinged flap in the top of the bonnet, all this work to direct more air in to the radiator and engine bay.
The top flap is seized open at the moment.
I was just thinking the top flap would help stop vaporising too. A lot of the AWM pictures show the North South road cab 12s with the bonnets off.
