Juve did that write-up, so you are in good hands.
An interesting read, specifically:
4. Now, look at the back of the panel – on each side, where the combo gauges live, you see 2 black football (or rugby ball if you are in the UK) shaped objects with a brass nut in the center. Loosen these with the socket. After you have gotten the nut and washer off, lift the football shaped thing off of the circuit board. – these are the main electrical connects for the combo gauges.
5. Clean the nut, washer, and the brass posts, as well as the threaded post sticking out of the circuit board with metal polish – then wipe down with alcohol to remove any residue.
I was not aware of those football shaped dealies. The only thing I have cleaned in the past were the cable attachment points. I learned something new today.
As your sig mentions a early-model 944, this walk thru might be a bit more applicable for cluster removal (deals will removal of speedometer cable):
