I have 1995 z 28 driver mirror has the interior adjustable **** inside. Parts on inside r missing trying to figure out what part and where does adjuster mount. Thankz

 

If I'm understanding what you're asking correctly, the mirrors are controlled by a switch mounted in the top of the same panel on the door as the window switches. I doubt these parts are still available from a dealer. Best bet to finding what you need is probably looking for them in a salvage yard.
