All fixed, managed to get the crank pulley off this morning and fit the 1.8 pulleys, this evening I got the 1.8 alternator in and everything back in the engine bay including fixing that coolant leak from the rotted 6mm pipe I disturbed, it was going to go eventually anyway.
I now have a steady 14.4v with the lights on or off which is much better than before. 1.8 alt is bigger and needs a larger ring connector which fortunately I had.

ribbed belt is a better design too so it solves the v-belt 1.6 issue aswell.
Nose on in the morning and then fit the 300lb springs and take it for a drive I guess!
