It depends on the original cluster you have in your 1995 C280. The MB C class clusters were changed in 1995 and if you have an old style C280 cluster and new style C36 cluster, you can forget about it. (Although I am convinced that I will succeed one day…)
However, if you have a new style C280 cluster (adjustment pins at the totally left and right instead of halfway the cluster), it becomes fairly easy and even possible.

I have tried my 1996 C36 AMG cluster in a 1996 C220D(iesel) and was surprised by the fact that all gauges and check lights were behaving perfectly. It is no problem that the speed gauge has a different reading; the needle was pointing at the right speed (but would never reach the right corner anymore).
The rev gauge needs a different reading to be stuck to the base plate (these reading gauges are just stickers that can be exchanged after the needle is removed)...

Now tell me; does your C280 have an old or new style cluster? (you are already the third person that asks about this on the different forums...what's up with those clusters?)

jjrodger; you have read my website very well!, thanks.

greetingz,
