I had (well, will have again) a radiator from a 80 300SD I parted over a year ago. I sold it to someone two days ago who just informed me that his mechanic told him it leaked. It didn't leak when it was pulled but I did move once so it could have easily been damaged.

I'm planning on giving him his money back.

Now, the question. There is a 83 300D at the junkyard. The radiator looked to be in good shape. Are there key differences in the size of the radiator?

Could the 123 radiator work in the 116? If so I'll tell him to head to the junkyard.

EDIT: I forget the year of his 300SD but I know it is a 116 300SD.
