Metro Area Glass Shops

Having a stupid hard time finding a simple replacement diffused downstem of decent quality for my zob. Went to Illuzions glass, great selection of everything but no 18 on 18 diffused downstem in 3 1/2 inch. Tried to sell me a 14 on 18, but then i would have to get a new ash catcher too, not looking to spend that kind of money.
So where does everyone here go to get there glass? Any one know a good place for downstems? I would love to get the options of pierced, slotted and showerhead in the same place, but i don't know where to look.
I plan to go this weekend to find a piece, so any help on this would be great!

No one here has a head shop the like?!?
Any help here would be huge.

try mad hatters smoke shop.

Bro! Heady glass. Look no further. Ask for chris. They are the best shop I've ever been too with two to notch artist. tell em I sent you.

Thanks guys!
I already hit up a guy at heady (probably chris) and he said they were out of stock on 18 on 18s too. Found a piece to get me through until i have time and want to drive all over the place to find the right piece.
I had forgotten about Mad Hatters, i will look them up.
