These are offered by KL7FZ. They are about 8 3/8" long, 3 3/16' wide and 1 1/2 " tall. Fins about 13/16 " tall. There is a U channel below the fins. This sink is removed from cell service, and has a 50 Ohm 150 Watt load resistor screwed down in the U channel. The link has a good photo of the part.
The following link shows all of the items listed by KL7FZ, cables connectors, and various small do dads from cell service :
