No. But you should be able to make a 6m stub at the base. Take about 5 1/2 ft of aluminum tubing 1/4" to 1/2" dia, flatten one end with a hammer for about 1" and bend the flat out sideways at 90deg to the tubing. Then use a tubing bender or pour some sand to fill about a foot of the tubing at the flattened end and put the sharpest 90deg bend about 4" up from the flattened end you can do without kinking the tubing. The sand inside the tubing will help avoid kinking. Then hose clamp the flat to the lowest part of the antenna main radiator right above the insulator near the coax connector.
What your trying to do is make a 6m resonant element that starts at the base of the Hustler and runs parallel with the main antenna tube but about 4" out from the main antenna. You can make an insulator out of a 5" long piece of 3/4" PVC pipe drilling a hole at one end that will slide over your new element then two slots at the other end so a hose clamp will pass through so it will hold that end right to the antenna main element. Then use an antenna analyzer to trim your new element down to resonate where you want on 6m.
