My '96 S10 Sportside pickup's driver's door slide-lock mechanism (plastic) that allows locking and unlocking of the door from the inside is broken and I'm looking for a replacement. Not even sure what to call it but it shows red when unlocked and grey when locked. The black actuator (plastic) on the back of the part broke off so now does not work. Tried to JBWeld it back together but it only worked for a short time before coming loose again. It has an opening which the door handle operates within and is held in place by one screw under the handle. Thanks for any ideas on where to get this part (or maybe even what it's actually called).
