Used--this input gear has a single marking band on the flat shoulder and also mates to a different 2nd and 3rd gear with 2 markings on teeth as fitted mainly for economy versions of vehicles-mainly metro and few 96 on MPI mini variants.
If you cannot find these late SPI/MPI drop gears a desperate alternative is fitting earlier drop gears in a matched set-with correct engine size primary gear, idler gear and broach gear from earlier A plus gears with one marking groove
