My son has the old BCD with the older integrated weight packet with the yellow plastic pull knob connected to flex strap connected to the weight packet. Then there is a white plastic string like connector that goes to the BCD to secure the weight packet. Can someone let me know were I can get a replacement for the scuba shops have not been much help? I did not see any online and don't know a part number to search. This BCD is not used much but over 10 yrs old and still in good shape. Thanks.
