I have an 83 K10 that started life as a diesel. The original diesel radiator sprung a leak, so I replaced with a gas radiator, the issue that I am running into is that the upper mounts are different, and I am having a heck of a time trying to find them. the only one that I have found online is the big rectangle one (which does not work on my truck. I even went through the local junk yard, but every truck has had the radiator pulled and the mounts are gone. Does anybody know of a place to find these? otherwise I am going to see if I can modify the diesel ones to work on the gas radiator.
