The 83 300SD engine is the same as the 83 300D, the SD uses a electric sending unit for the oil gauge, and the 300D is mechanical. look at the rear of the oil filter housing.

the eng mount arms I think are different, but just swap them. one eng is a 617.952 and the other is a 617.951.

the 126 uses a electric sender to the spedometer driven off the rear of the transmission. the 123 uses a mechanical cable drive.

the oil cooler lines might be different.

the block is the same, except for a few out side add on`s.
