Upgrade ignition system components

I'm planning a couple of trips to Europe this year and so in the interests of avoiding possible problems I decided to upgrade the ignition system components. I think the ones on the car were original and so could do with an upgrade. Also, as everything was working the old parts would make ideal spares.
The New Parts
I decided to replace (ACT Part Number):
Replacement Process
I started with the rotor arm, it's just a matter of removing the distributor cap and then it's a pull-push replacement.
Next I replaced the distributor cap, I marked the location of the number 1 feed and then switched them over. Then using the diagrams in the bible I worked through each cylinder as follows:
Replacing the coil was fairly straight forward but quite fiddly. Just undo the two securing bolts taking care not to drop the nuts / washers (which I managed to do several times). The connecting wires only go one way, there are two male and two female spade connectors.
After all that I was sure that I'd have missed something or not connected something. However a quick test-drive revealed that all was well. I think that the engine felt slightly smoother but that's probably just the "I spent money on it so it must be better" effect!

- Removed the old lead and plug extenders
- Connected the new plug extenders to the leads
- Attached the extenders to the plugs
- Routed the leads to the distributor
