Door Handle Help

[trentwat]

Hi Pelicans...Broken bits in the door handle...car (‘88 911) is in the body shop; and to get a better buff, my guy suggested we remove the door handles; and that I could clean the mechanicals while they are off the car. Took them apart, and found a tiny broken black o-ring around a white plastic element (yellow box); as well as a thin black plastic barrel around the lock cylinders that brushed right off (green box). The Porsche parts diagram doesn’t show these parts. Where can I find replacements?

Is anyone familiar with these parts...especially the one around the lock cylinder? Maybe I could 3-D print something, but I need to know what it looks like (and measurements). Thoughts?
