Lens Replacement questions

I have a Phoenix 75mw Green laser from WL
the laser was not nearly as strong as it used to be, so i decided to clean it, and got a tad of alcohol under the lens (its not glued 100% around the lens to the metal)

So then i tried to unscrew the lens and as i went to unscrew the lens popped off, and the threaded part didnt move.

so i centered and reglued the lens, but there is minor dispersion from the laser dot, and the lens has a crack, not to effective on the laser point, but its there none the less.

how can i figure out a replacement, and how to install it properly?

there is somebody here that can fix it for you... but i don't remember their name. if you don't get answers right away bump this thread from time to time.

sorry i couldn't be of more help
