Slow weekend. I checked the EPC. All varieties of US spec passenger car 603s; 603.960, 603,961, 603.970 and 603.971, use the same crank damper part number. Swap away! However, because it's a rubber part, and maybe even if it weren't, it's prudent to verify that the TDC indicator indexes TDC on the damper with #1 at TDC.

Thanks Sixto.

One more thing I can check off the list.
