NOTE: Made to Order - If you are interested in a specific design that varies from this, please email us at email@example.com. If using AN lines we also recommend designing the upper radiator hose so that there is droop/ give so the engines movement and does not push/ pull on the radiator and fatigue any parts. Fill tube is welded so that it sits level when bolted to an engine with a 15° lean back (exhaust side).
