Forgot to mention a few more small steps in my last update.
Fitting the Dynamotor highlighted an issue in that it was sitting about 8mm too far forward and the belt was therefore out of line, managed to h=get the end of the front mounting lug turned down 8mm and combined with 8mm of stainless washers at the back it now fits and lines up so fitted the belt, another small victory.
Also fitted the rocker cover.
TTFN
