After 2 years of occasional speedometer failure, I recently had the instrument cluster replaced with a used unit. Turns out, the supplier sent the wrong part. And I haven't been able to find the correct part at another source. The problem is: speedometer now works correctly & consistently, but the tachometer reads too low. My question is whether it is possible to replace just the speedometer head in my old instrument cluster, with the new (used) speedo head, leaving the old (functional) tach in place?
Any help would be appreciated. Thanks, Daryl
