You have the carberator thing reversed. The 80s ones are feedback ones that need the computer unless its a car from Canada. The 70s ones are more normal. But no matter what one it is you still need to change it because none of them have the right port for the distributor and the leanburn ones are setup differently. Imperial should be fuel injected but I think theres more to it then just putting a carb on it and the distributor and ECU. I think the kit to get rid of fuel injection used to be pretty big and had a lot of stuff in it and think the digital dash is different too. Thats what Ive heard anyway Ive never done anything with one before.
