Door guides/grommets? Where from?

Hi all!

Can anyone help with sourcing the missing parts for these holes on the doors of my 3 door GTi please?

What do they look like? Any help would be gratefully received!

The Model year would be good to know as you and us can search the ETKA for answers as to the part numbers.

Ah yes! Apologies, my telepathy is failing me these days…haha
It's a 1983 'Y' reg. GTI body shell.
Thanks for the link for ETKA! Very useful!

That was where the passive restraint latch was bolted to on my 81 Diesel Rabbit over here.
The Belt with receiver pulled out of the inside of the seat and   latched to the door frame.

Interesting! We didn't get that feature this side of the pond…possibly they just fitted closed/blind grommets in these holes then? My other thought is that they might have a kind of "anti-rattle" bumper/bung that coincidently lines up with the recesses (as pictured) in the B pillar??

Trying to recall what my old '83 Golf Driver had fitted….but clearly my old aging memory is failing me! Gah!
