it's been a while since i did one, if i remember right the wood comes off via a couple hidden sliding latches on the bottom (if i am thinking about the right one, or its screwed on) the biggest pain in the ass with 190 ac panels is the fact that every year and model has a different part # cci uptime/programa does some good rebuilt units for those cars, for some of the other annoying **** like the fuel pump relay and climate control relays their replacement stuff is way above the benz **** in quality. keep good oil in that thing keep it changed and be mindful of self destructing timing components, cam/rockers chain/guides, if caught in time you will spend considerably less money then if you ignore it
all america wants is cold beer warm cat and a place to take a poop with a door on it
