CHRIS.O said:Wish I could help David but I have never had a factory tach in a g body. Never had the dash that far apart either. I would rather have the factory one if you can make it work. Never much cared for an aftermarket tach unless you need one.
DoubleV said:The Cutlass tach is set up the same way as the Pontiac one.
Bonnewagon said:Thank you DoubleV, for that info! Now David, all you need to do is to CAREFEULLY remove your cluster and reset it for 8 cylinder use.
Bonnewagon said:Again, I'm not an Old's guy, but usually you can pull a GM cluster out by first removing the lower dash panels (by your knees), and the outer dash panel (facing you), to get at all the hidden screws. Don't miss any and don't FORCE anything. Then CAREFULLY reach behind the cluster and unclip the speedo cable. If you have cruise control,unscrew the cable at the CC box and pull the cable through enough to unclip it. Then unplug the harness and pull the whole tach/speedo/gauges cluster as one piece and do the fix. On my car I have to drop the steering column to get the dash panel off, I don't know about your's.
