Well its in and running, lovely smooth idle picks up well, not a single missed spark so far.
build quality is as good as original if not a bit better, but the the original is 20 odd years old so no surprise it looks shinier. The leads that came are monsters i was replacing some 8mm silicone ones and they were dwarfed by the new set, plenty of length too which is nice, i will dress them in properly tomorrow.
the only issue was the amp being on the side of the dizzy but with some jiggery pokery i managed to leave it where it was on the dizzy and still get enough advance for the timing up, it would foul under normal installation but remounting where LR put the original would soon cure that but as it stands i will leave it where it is on the dizzy for now and monitor the heat build up around it. I have plenty of spare amps now anyway so if it needs to be moved or is effected by heat too much im not massively worried about that for the time being.
I didnt fit the new coil that came with it as i had a brand new coil already fitted and it started and ran well enough with that so the new one has gone in the spares box.
so all in all i would definitely recommend the bundle deal at the moment, delivery A1 and build quality and instructions a solid A, we will see as far as performance goes but at the end of the day a disco isnt exactly a sports car, all im looking for is a solid reliable ignition system that keeps things firing as and when it should and for the price of this set up i really cant complain.
