Quick update:
No actual progress made on the car but I've just been through the boot today and found a load of stuff:
Some amp wiring

this could save me a bit of cash when I get round to doing my ICE:
Belts, tensioners, a dizzy and a clear dizzy cap:

I found another dizzy cap later on too.
I also found a couple of these new in packets; anyone know what they are?:
And a brand new stabiliser link:
I can only assume from this that the belts & tensioners will need doing soon, there's been some dizzy problems, and one of the stabiliser links has been done (as it says 1 of 2).
