Okay, so here we are with the cluster that we are going to modify:
This is an '86 560 SEC V-8 so your may look different.
So how you start is by taking your LSD (Little Screwdriver) and slip it into the lower sides of the cluster and GENTLY pry it out.
[Correction Re Ross: I use a LSD on mine because it pops right out "Zippered" like Charlie's however Ross is correct, use or make the hook tools to get it out if you have no obstructions like Kurt did with the cap in place. Thx to 420SE for the correction!]
Kurt's has a dash cover on until we tear out the interior and replace it with the new factory cover he has. This type of cover though may need to be pried up to get the cluster out.
Okay so here is a pic of the back before you dis-connect it. (looking fm pass side)
And once the cluster is out:
The big round connector on the left os for the 4 way gauge and may be a little difficult to pry off. Go slowly and use your LSD if you have to...
Here is the cluster out and the rings from Perfomance Products:
There are ones available, but these are high quality and metal. Who knows what the eBay ones are.
Here are the rings and the decals. The Decals are very high quality and well made and he makes them in many colors. (Yes, Pink DG!)
Here is the back of the cluster and the Speedometer in particular,
Okay, here is the outside temp gauge and it's two screws:
Remove those two screws and take out the TEMP Gauge.
The light with the wire attached is for the Water level. CAREFULLY remove it and pull to it's side.
