It is cut not sure why they would do it.
Yes it is aGMC. The rad on the GMC chevy did not have a neck. Gmc rad sits flush in the support chevy sits in at the top but slightly slants out at the bottom. This is obtained by the way the flanges are welded on the rad. Also the part that goes up and over the rad is gmc only. There is part missing that looks like half bowl if you will. They are very hard to find
