I have a Performer that the wife picked up for me about seven years ago now. I use it almost strictly indirect with the coal bins. What I like to do is flip the grill grate upside down and let the two grate doors sit against the inside of the bins. This makes it super easy to add wood, and it also helps to keep the wood from missing the bins.
Sorry about the short rack, it's just the wife and I now
I also took dimensions from my brothers rotisserie and had my local tin smith bend me one. I measured from the coal grate to the grilling surface and from that I measured up the ring and put in four 1/4 20 screws. Now I can use another grill grate at this second level and double up what I'm cooking. That makes for a lot of leg quarters! I also use this grate upside down and have a nice wood shoot to the coals.
The two levels seem to cook very evenly and if your doing beer can chickens it's great to have the lid away from the birds.
Lastly I recently picked up a stainless pan that I know not what it was used for, but it has lips on both sides that lay on the coal rack edges perfectly and still leave about a quarter to five sixteenths of an inch between the side of the pan and the coal bins. I fill this with water and it flat-lined my cooking temperature. The grill grate sides sit inside the pan about a quarter of an inch and keep the wood chips from falling into the water.
Sorry for the long winded post.
