Howdy and welcome, Street.
LOL @ "chicks dig scares" & "gnarly biking accident" Just glad your on the mend. Scary stuff! Imagine that at 30 MPH and under power. I had a foam filled helmet save my knoggen when a front fender let go. Front wheel stooped and me & the rest of the bike didn't. Over the bars and face planted. (but I stuck the landing)
My 1'st thought was "great, Carol will be spoon feeding me and changing my diapers from now on" Sucked, LOL. A neighbor scooped me & the bike up. 2 doors down from my house. I repaid him by bleeding all over his cab and spilling gas all over the bed of his truck.
All that to suggest that liquid nails is not the best option for shoring up fender mounts. The vibes shake em off. Just not made for the riggers of motorizing and running.
Lots and lots of different approaches to beefing em up, here on the funny pages. The mounts, I mean.

Again, welcome and really glad you're OK!
