Powerbook G3 Pismo Firewire M7572 400 500 MHz Hard Drive Caddy Ribbon 632-0116-A
Carefully tested, not just guaranteed.
The translucent plastic pull-tab gets brittle on these vintage caddies, and may be broken.
Of course this does not alter the function.
If you need the mounting screws I have them available for $5 more, and will refund the $1 shipping cost.
