You can make the bead on the end of the hardline in 2 ways, You can weld a tall bean all the way around the tubing or you can buy the tool to form a bead on the end of it. It can be tough to do this in stainless tubing without a tough bead roller. But aluminum tubing rolls like butter.
The biggest your going to find in AN is the #24 when you can find it. #20 is pretty easy to find and get all parts to go that way. If you plan it out that way when you buy the radiator most places will put #20 fitting there from the get go. I usually do the upper hose in AN because it looks slick. But it can be just as spendy as building a stainless hardline.
