Hi,
I ran across this link a longggg time ago but it's a great detailed writeup for modding a Brinkmann. The guy makes legs, vents, and brackets along with a whole bunch of food pics. Some of the ideas may be be applicable to Mini WSM, SJ, or Kettle projects so If you are the DIY type I hope you get something out of it.
