the 200 has a cylinder for the air cleaner, the 300 a flat pannel shoe box.
The 300 safari uses the same hole as the 200 in the inner wing but has a moulding that wraps around the side of the square air box in through a new/seperate hole. The original hole then gets plugged.
Nothing stopping you adding a bit of flexipipe to the 200 snorkel to make it fit, or try to source just the moulded part... I imagine the rest of it is the same...
