the later lights with the twin head lamp blubs and the indicetors in one are not easy to do to a early td5
but from what ive heard the tdi300 and the early td5 use the same headlamps
so what will be involved in fitting them will be triming of the front wings
some triming and drilling of the front pannel behind the head lamps
maybe even abit of triming of the grill
som one has done it in the march lro put them in a disco1 v8 looks good
