1982 front Seat belt receptacle dilemma
 

I have a US 1982 300CD. The seat belt receptacle plastic covering is cracked and falling off. The plastic to too brittle. I'm looking for new ones. I found some on eBay. But, the different receptacles look too similar to know if I'm getting the right ones.

The ones I need will accept this latch. Does anyone know the 123 part number?
