custom chassis, and front of the car is a 1 piece fibreglass mould. so it should fit, and if it doesnt. jigsaw time yeh ive been looking at that, will help with not having to cut front open too so a lower class... I thought id be racing in EFI or SS/BB or am I wrong? cant argue with results is this the kind of this I should be looking at? if so, what brands should I look at? http://www.pwr.com.au/coolers_atoi.html
