:eekAnyway, I once almost made another 123 purchase, and the car had a "torn" hinge bolt...When I had the compression tested by a local independant specialist, he informed me that there is (was) a REPLACEMENT rivet....This part consists(ed) of a special bolt and washer assembly availible thru the dealer. The $ price was said to be MINIMAL for the part...
Maybe someone else with access top part numbers etc. will chime in.
Good luck with the 300D.
best wishes always, and lets keep those diesels firing,Spo out :
