Upper Radiator Hose driving me crazy

[cst350]

I have been trying to replace my upper radiator hose on my "69 small block. The old hose has a number printed on it. I have owned this truck since 1980 and know its history. The hose was correct when I purchased it. BUT NOW the same number gets me a different hose! WTF!!!

Check out the pictures below. My old hose is the one on the bottom. The PN is clearly visible 3947120 UT. The new hose on the top has the same number printed on it but is the wrong shape. BTW this is the third hose I have ordered from different suppliers, all have been the "new" shape. I am also including a picture of my truck with the hose installed and also a pic of a bone stock truck I found on the board.

I am hopping someone on the board knows where I can get the original shaped hose.
