I am going to install a sno pro hood on my 1978 srx 440 and i know about the thermostat housing clearance and the radiator clearance, but one issue i am not sure about is the air box? Will it fit? Or do i need to run velocity stacks with screens? If so where can you purchase these stacks? the air box side of the 38mm mikuni's I am running is 62.25mm any help would be great. Thanks
