IIRC M103 and M104 fans are in the same location.  V8 fans look to be offset like the 300D but I don't see 2-piece shrouds in the E420s on eBay at this moment.
lt1fire, the 90-91 350SD/Ls on eBay don't show a 2-piece shroud but my '91 300SE had a 2-piece shroud. In the case of the '87 300D, MB superseded the single piece shroud with a 2-piece shroud so that's all they sell now. Check the EPC.
