Lower radiator hose - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Getting ready to install a new champion radiator in my 70 gmc c1500. I figured out the top hose but having some issues with the lower. I see there are 2 options 1 with factory ac vs non ac. Mine was originally a non ac truck i believe but someone added classic air and switched to a later 1 piece seal block. I am looking at whats in the truck now but looks like it might not be right. Right now it looks like its a non ac hose (gates 20582) but the fit looks sketchy at best. Wondering if anyone knows a better hose to run.
