I can get a picture, but due to my schedule, it will be a few days.
I've had the radiator off several times working on hyd pump issue. My 2000 also has a rod that goes from the top of the radiator to a large stud on the block.
I can say that at least once I forgot to put the bolt in that holds the brace to the radiator housing and I ended up loosening everything back up to get the brace lined up. Yesterday I changed my oil, and I took the plate off and gave a tug to the radiator assy and didn't detect any change. The other side has no bracing of this sort....
However, it didn't take long to get the plate off. In the past, I fought with the drain, but I popped the two bolts holding it to the plate off. That would be a total of six bolts to remove, which goes fast with a ratchet, they aren't that long. You dont need to remove the two off the drain, so it could be four bolts. In other words, I'd leave it.
