^^^ The assumption made that the one clutch is for the 6 blade steel fan and the other clutch is for a 9 blade plastic fan is incorrect.

I have an '83 300D with engine number 12 40xxx and it originally came with 6 blade steel fan. The Behr clutch part number for that is 0002001922. Same part number for all later 9 blade plastic fan clutches.

300D
For models with engine serial number through 036024 - Behr part number 0002000422

For models with engine serial number from 036025 - Behr part number 0002001922

EDIT: Added addition model info.

300CD
For models with engine serial number through 003977 - Behr part number 0002000422
For models with engine serial number from 003978 - Behr part number 0002001922

300TD
Information I have is all engine numbers - Behr part number 0002001922

300SD
For models with engine serial number through 039510 - Behr part number 0002000422
For models with engine serial number from 039511 - Behr part number 0002001922


The description from the above link of it being a centrifugal clutch and coming on at 3,000 rpm is totally incorrect. I wouldn't trust the assumptions on that post.




But getting back to your question, I have two good 0002001922 clutches with 9 blade fans intact that I can sell for 60 bucks each plus shipping.
