I just purchased a '87 Z-24 with the electronic gauges. All the gauges work well, but the tach does not work. Is there any little problems I can check for before I start searching for a new gauge cluster. Anyones help would be great. Thanks.

i find the digital cluster in general is junk. you can check the tack filter, and see if you have a tack signal behind the cluster (its the white wire, i think its the top left pin on the plug). im guessing you will need to find another cluster.

Thanks, were can I locate the tach filter. I tried to remove the cluster today but could not get it out because the steering column is in the way. Will I have to remove the steering column to be able to remove the cluster? I was also wondering if these cars had a hydrolic cluch or not. Mine is a 5 spd. and someone told me it could be ajusted to grab gears faster. If they are hydrolic I dont think it can be ajusted. Thanks again for your help.

It is possible to remove the cluster w/o messing with the steering column but its a PITA
its a lot easier to remove if you lower the column after all its only 2 bolts
