Hello
If i understand you right, you have a Mercedes G 280 wich you want to put back to the original.
And you need some special informations wich kind of Radio and Lightbar you need?
Is this right?
How you can see in the following Links, the Speaker was a RTK 3 and the Light was a KLJ 80.
Both from Hella.
