Dizzy cap and rotor arm please urgent HELP needed

Hi everyone, so my car has stopped running, it's extremely difficult to start and when it does it won't idle and cuts out. I am ticking things off that it might be and I thought I'd change the dizzy cap and rotor arm. The only trouble is it looks like there a few varieties and I don't know which. The car is a 1983 mk1 GTI tin top running a DX engine. I know the dizzy cap is not the pin type and I believe the distributor is bosh. What cap and rotor a do I need? Please help as it's my daily drive and I need to get to work  

I've just changed them on mine, is 1990 though so might be different? Photo attached of what I fitted.

Hi

If it runs for awhile, won't idle and then cuts out, it has a spark, it is more than likely the fuel / air / vacuum / timing related.

CHECKING SPARK
Check the spark 1st before changing the distributor.

take out a number 1 spark plug, connect the plug lead and rest in the engine lift eye (arrowed), or on rocker cover to earth.

Turn the ignition key to start the car for a couple of seconds and you will see the spark, helps if in garage or dark.



The spark should have a blue color, like here:
