Sure looks like it should work. If the SMA connector snaps in I would think you'll be fine. You said it was marginal with the smashed antenna, even if this one isn't perfect it should be a lot better.
Looking though the .pdf spec sheet I noticed a predicted 5 MHz drop in center frequency when put in a radome. Makes me wonder if the ones being sold without a radome would work better if we put them in one. They also specified the gain figures with a 70mm ground plane under the antenna, FWTW.
The antenna bandwidth is pretty wide, so without a radome you'll have lower gain and higher SWR (or return loss). Without the ground plane the gain will probably be lower and the pattern slightly different? I'll have to talk with some of my other radio friends to get up to date on this stuff.
But my money is on it working just great
