So as I was shifting into reverse yesterday, my stick just fell off! So there's a little nub left by which I can still shift gears, the end of which is rubber. I can partially put the stick back on it but it is wobbly and I can't get it all the way on. Am I missing  a part? I'm thinking trying to force the stick back on with a mallet would be a horrible idea. 

Car is still running and I can shift gears so it's not the worst thing in the world, but trying to shift the little nub with my fingers is pretty rough and sometimes inaccurate. 

Anyone had this happen? Any ideas? 

Thanks in advance!

Easy fix, unbolt it from the Trans and pull the support rod out of the rear rubber mount.

Grab a good used one from the yard.
