pick your DiscoII and get the 8mm wires. The 8.5s are more than you need.

 

I just did mine today with Magnecor 8mm and Bosch+4's. I did it without taking off the IM. I bought the gasket just in case, but I did not need it. I was able to do it by lying on top of the engine. It is easier if you remove all the wires and match to the new ones and install. The drivers side wires are slightly shorter than the passanger sides. Pay attention to the wiring diagram and you can do it. I bought my wires from Apexperformance.net shipped for about $95.
