I'm helping a friend swap the lines that run from the oil cooler to the sandwich plate and i need to know what size the fitting on the cooler itself is. We've managed to get the size of the plate figured out which is M16x1.5, we just need to know what the size is on the cooler end. He managed to mangle one of his lines somehow so we're just going to relplace everything with braided line and AN fittings.. Thanks in advance.
