Aside from swapping EPROMs/ circuit boards, etc on these things, swapping a 986 to 996 cluster is not a big deal at all if you have access to a PST2 or PIWIS.

I guess what you did here is FAR more involved, since you started with a damaged 996 cluster, but all this work is not necessary if the 996 cluster you want to install is good, as all you have to do is code it to the car with the PST2/ PIWIS. This is also how you program the 996 cluster to be a C2 (vs C4) for proper fuel level calibration, and how you get the convertible top light to work (coded as C2 Cabrio).

The only thing you cannot do is re-code the mileage (this only works with a new cluster that has under 60 miles on it). Supposedly Palo Alto Speedometer can re-code the mileage, but I haven't tried this.
