Help Identifying

[BodyShopDropOut12]

Now that I finally got pictures I can try to get some help with this. A few people have told me that it may be my tranny cooler, but it is in no way hooked up to my transmission. Thought maybe an oil cooler cause it almost looks it. I can definitely tell it ain't stock cause someone cut up the frame to fit the lines into rails, and its kinda a messy job that was done. It was mounted inside the radiator support just in front of the radiator. The hoses are goin to the back, sittin inside the frame rails. The one on the passenger side leads to a pipe that is just hanging at the fuel tank, and is connected to nothing. The drivers side is connected to some kind of outlet/inlet looking valve on the rear, which as shown, is connected to nothing also.

If someone might be able to help identify it, would be very helpful. If I can get a hold of a camera I will take better pics as the engine is out now and bed is off. Thanks

P.S. - If needed, 1980 C30 w/ 350, sm465, 14 bolt 10-1/2"
