Ok so i go to chevy parts and ask how much for this part. outside door handle for a 06 chevy extended cab. it's actually inside but they call it outside. part # 15758172 $70.10. wow so i go on line and look.
part 15758172 is interchange NR Partslink GM1520115 $17.99 quite a difference. so i ordered it came to $23.13 delivered to my front door.

here is the info on the install. 2 star screws, i got a collapsable set like allens at harbor freights for around $2. would you believe i had everyone but that one.
remove screws, install new handle. no clips or nothing. retighten you are on your way. handle comes complete and ready to go.
i got mine on Amazon.com and it came from www.vehicle-interior-parts.com
hope this helps
Jim
