Hi, I'm looking to buy replacement carbs from a friend and I'm not 100% sure if they are off of an F3. They look identical, and they have the electronic TPS. My question is can it be possible that they are off of an F4, and if they are can I still use them, any help is greatly appreciated.

 

F4 carbs? Rack won't line up.

 

from kuro's post awhile back, f2's wont work either as they aren't made for ram air (although i think they line up fine)

just an fyi
