Looking for rattles and tubing

We used a guide down on the coast for several years (he retired and I can't contact him). He had a weightless croaker rig that consisted of a rattle attached to the line with a piece of tubing, a swivel, the leader and the hook. Does anyone know where I can purchase the rattles and tubing? I know that they have the newer rattles that have a place to attach the main line on one end and leader on the other end....I am not looking for these...I like his rig better
Thanks

TEXAS RATTLER™ make a weightless rattling hook:

Fish-Max

Any place that sells rattles for jigs and lure making like Barlow's tackle for the rattle. Secure it to the hook with some heat shrink tubing.
