'95 suburban k2500

Having a hard time finding the handle/release for the left barn door. Handle is mounted on square plate. Accessed when right barn door is opened.
Anybody know of a vendor and or correct name for part. My googlefu is weak today.

 

LMC Truck (LMCtruck.com). Cargo Door, Inner door handle. $69.95!! I'd go to a junk yard first at that price.
