Yes, why did you feel you needed to replace the original cluster? Some cluster issues are easy do-it yourself repairs, while others need to be repaired by specialists.

The original instrument cluster clock setting switch failed, so I purchased a used 500SL cluster thinking they were interchangable. Turns out they aren't, speedometer calibration way off. Then I moved the clock setting switch to my original PC board, successfully, but broke a couple of ribbon cable connections in the process. Repairing the ribbon cables turned out to be a tail chase. Repair one and two fail. Now it's working, but I feel that the PC board is like a bomb waiting to go off.

That's why I'm trying to replace it.

To 97SL320 and tecqboy,

Thank you for your comments and advice. I finally got into the Mercedes On-line parts catalog, and found that the 129 540 71 48 is currently listed as the replacement panel for my '91 300SL. So, I cabled it, tried it and everything works! Speedometer and tachometer appear to be properly calibrated. Resetting the Electronic Odometer will probably require a Mercedes shop.

Thanks again, Bob Deming
