After a few thoughts on the matter of flushing I decided to use some degreasant which is very thin so I used around 1/2 pint and give it a good swirl around inside tipped it out and repeated the process, then tipped the full pint in and did the same .....there were a few bits of metal stuck to the magnetic plug but no more than you would expect from a used gearbox (we have all ground gears at sometime or another).
Couple of days ago I managed to fit the gearbox with the speedo sender being the only fouling issue (whilst trying to move box backwards) but was resolved by removing it then move the box to its final position then re-fit the sender (just).
prop shaft fitted perfectly, so now I must make a start on re condition of engine but before that I will need to shorten the clutch yoke as it fouls the footwell at the mo, I think taking 6-8mm out of the length will render it clear then work out the best position for the slave cylinder.
