How do I replace the hood open stay assembly

I have a 2004 V6 Honda Accord. Both hold open stay assemblies are gone bad. I bought P/N 74195-SDB-A02, the delaer told me that they are improved replacements. However, the connection on the new ones are different from the old parts. The old rods are connected to the car by ball joints and I cannot remove it. How do I do this? The new parts have a clip that makes it easier to install.
