djdsc, Thanks for those pix. Now it is beginning to make sense.

goldrunner - from these pictures, I see what gets Dremel-ed out - the pinched crimp of aluminum holding the spring in the slot, right? Looks like those three large counter sunk holes are the monut points for hte whole deflector assembly - or at least this portion of it. If thats all, then gettingit off the car is a no-brainer. Still not sure about the little "bumps" as you describe them. I'll have to do my own little bit of forensic work.

But it SEEMS like:

Grind the crimp out

Use a small tool to remove the spring (which also functions as an "axle" or pin for the broken hinge part).

Replace hinge part with new and (somehow) reinstall wind deflector to match non-broken side.

Is that about it? Are you saying a strategically placed small blob of JB Weld holds the thing together after it is done? Either that or a new crimp using some unGodly powerful crimper or maybe a chisel...though that sounds crude and heavy handed. Process sounds like a winner.
