1957 Transmission Cooling lines- Early or Late?

[Jimmyh54]

I am trying to order new oil cooling lines for my transmission on my '57 bird. How can I tell if I need early '57 or late, as one set has a "hump" and the other does not?
Thanks
Jimmy

If you summarize your post in your subject, you will get more responses. "1957 Trans Lines" could mean anything. I will update it,
