I just did my Dis pack. I took the scuttle, plenum, the top part of the injectors, the idle speed adjuster valve and the plastic wiring harness carrier. I then used cable ties to hold as many of the vacuum pipes etc over to the drivers side of the engine bay as I could to give clearer access.
To help me remember what went where,I marked things (like plug leads)with correcting fluid as I went.
This might seem a little excessive but it gave much easier access to the Dis Pack without the need to rip all the skin off my hands. In fact I was pleasantly surprised how relatively easy it was to remove.
E10 torx. The screws are long so you don't have to worry about losing them, undo them fully with the tool and then finally take them out by hand. The front one on the passenger side is tucked away so I put a small piece of kitchen towel over the socket so that it made a tighter fit on the screw head, so I could lift it out still attached.
I know I should have replaced the seals on the injector assembly but I confess that I didn't.
