The oil cooler is easy to rebuild . You can bang the ends off with a rubber mallet. Just use a lot of vasoline on the O'rings when going back together. Mark each end before disassemble . Use a extendable clamp to squeeze back together. Most IH truck dealers have the kit for rebuild, whole lot less than $250. You don't need the one on Ebay. You have to get the kit anyhow . I've rebuilt 4 so far no trouble.
You may have to jack the engine up a couple inches to get it off, and slide in a 2x4 for safety.
Here's some pic's of one off a 90 7.3. I used a leather mallet to beat the ends off. 1st pic.
