Not an expert myself, but you should at least differentiate between NG and SK:
Mercedes NG (
Neue
Generation 1973-1988)
Mercedes SK (
Schwere
Klasse 1989-1994)
Mercedes SK II (1994-1998)
Sadly, Italeri never changed the old NG interior, so dashboard, etc. is completely wrong for SK.
And if you´re really want to build that race-truck, you should get in touch with a member of PMC-Dortmund (I could help you with that), who is currently working on one of those.
You wouldn´t believe how much work is needed to let that Revell kit look at least close to the real deal.
