1939 Ford flathead 59AB help

[hop up]

Can anyone give me info on the main bearing oil tube. This is the small tube that is 5/16 or 3/8 OD and has a bend in it . My buddy called and his is missing on his motor and ready to put the pan on and motor in. He tried to call a few places and no one had one including me. I figure if I get some more information on it I can machine him one. I dont have one to look at or measure. So if anyone has this info I would appreciate it. Thank you and happy Motoring
