Way ahead of you.... Years ago when I repaired the cluster originally! Thanks for the offer though! I'm sure there are many others that need to have it done. It makes a big difference in how the dash looks!

I also tinkered with the bulbs light tubes so I could actually see the gauges at night.

Anyone that has one of these cars should do both IMO.

The drive gear was in the transmission accessible with the trans installed.

The speedometer in my 85SD reads low when installed in my 84. The 84SD's speedo re ads lower still. I think the speedometer is entirely electric while the odometer is mechanical. I don't know where the pickup is located.

If you go back to the beginning of this thread this was covered, but not in detail. The little brass gear in my case was the problem originally as it was out of a different car with a different ratio (too many teeth). There is a picture of the "said gear" in post # 8. What "vstech" says in post # 30 is right on IMO...

This may help someone also. It seems to have been buried.
