I have a couple sets of matching keyed w123: ignition, door and trunk locks.
Good original condition, but not new

Can pull an ignition plug too.

Seatbelts yes. Specific year and post a pic to be certain of a match, they varied quite a bit

Good tested blowers, again need year/style.

And maybe a new oil pan gasket sitting around. We need to count the bolts on that one as well to match year/models.

I have the rest too in good used parts, but not new.

Plus, you can really save and come visit the piedmont to pickup
or wait till we come up for fall LEAF

PM me with interest in what you are still missing
