| This listing is for the coolant junction located on the right side of the timing cover. It connects to the lower radiator hose on one fitting. The other fitting connects to the hose that goes down the passenger side of the block and up to the firewall on the 75-76 z's. It also fits the L 16 4 cylinder engines. If you have a larger L engine in your 520, 521, 620 trucks or PL510 it should still fit. To find out for sure just measure the diameter of the top fitting on the junction and let us know what it is. For the hoses, gasket, bolts or Y pipe see listings or put a note in the comment section of the order form that you need any or all of these parts. We can add it to your order from our end at your request. We try to carry this part in stock at all times, but if we happen to be out of stock please allow an extra week for delivery.
