I have an old Brinkman Smokn' Pit Pitmaster which has no side firebox. I have seen a lot of the horizontal smokers that other people have and they all have the side fire box. I was just wondering if anyone knew if I could order the whole side box assembly from brinkman or another manufacturer, and rig it to fit on my grill, or if i would have to design and build something myself. I would much rather be able to find a side fire box and with a few mods attach it to my grill. The grill itself is in great shape, and is fairly well built, and i enjoy using it, so I don't really want to replace the whole thing just to get a fire box. I have no welding skills, or much metal work experience. Any suggestions would be great!
