Well the old ones are off- I was able to do them with just the flatblade driver dry.

It turns out that someone put a glue to make them stick, and that glue has caused mild surface rust on the bars. I should be able to get it off.

Any suggestions on getting the new ones to stick? I'm okay with epoxies or glues that will not rust the bars. I can always resort to the flatblade to get them off later, but I sure don't want something that will cause more rust.
