(first, thanks for having an awesome partfinder) I have this door handle set that I cannot tighten because one of the 2 bolts holding them together is stripped out. It's not the bolt itself, that seems fine. It seems to be the hole that the silver part sits in.
The white baseplate/hole has small channels in it that the sivler metal end bit (img_3777) sits inside and "grabs". The silver part is fine, it's the small grooves in the baseplat. The photo (3776) with scratched-up bolt will not catch within the female end because the small female channels that the flanges on the insert that the bolt threads into are stripped.
I believe I probably need to replace the entire white baseplate here....or re-order an entire handle set. Please advise. THANKS!
