Was cleaning out the garage a while ago and stumbled upon my grandfathers smoker and figured in memory of him and that I want to make some good food hopefully, that I would attempt my 1st smoking on fathers day.. pork shoulder.

Couple questions,
the thermometer is broken, where can I find a replacement for it?
from what I've found "The Brinkmann Sportsman charcoal smoker uses smoke, heat and steaming liquid to slow-cook foods." can anyone give me any good tips or hell I haven't found a recipe to try yet and Sundays right around the corner, and does

thanks
