crowsgmc,You need to know if you have the early 1955 261 or the late 1955 261. If I remember right,the oil pans are different.The early oil pan flanges curves around to straight line(the surface where the gasket is). The later 1955 pan one side curves around and jogs at an angle before it goes straight(the surface where the gasket is).I believe if you got the correct year of 235,it will match the 261 oil pan. Lets see what the experts have to say.

Correct me if i'm wrong .
