I worked on the airbox and started on the dip on the left side of the airbox to allow for the mixture control arm. I hogged out quite a bit of material, but I thought this was normal as the FAB instructions showed the modification necessary for fuel-injected engines. One thing they forgot to mention is there are two different types of mixture arms. The straight (the one I have) and the offset. The offset is the one you need and nowhere in the instructions does it mention this. The end result is two ruined parts: the plate that is bolted to the fuel servo and the top plate of the airbox.
