okay bit confused from that, but i got the diff today and going to strip and clean it down tommorow so ill take some pics of it, the diff came from a 1984 "carby" tarago so it will be a e-series but ill find the code so i know what ration it has, but have found that 84 models did cross over to EFI that year so as previously mentioned the e-series diff crosses over to f at that stage
