My radiator Which is original the plastic tank cracked. I ordered a new Delco radiator According to the Fitment chart this is the one that I needed it's like a 21 0 3 3 Which the AC Delco is as close to the original and so I could get. I added for about a month when to put it on it found out it's only a single row 1" thick Core which the one on my truck and is original is 2 and a quarter 2 and a 1/2 something like that. How can I find a radiator that has the dimensions for my truck that's not Is going to fail. My truck has a 114000 on it. Any advice or help would be appreciated parts are getting scarce For these trucks
