Just adding some information to my thread so I don't lose where it is in the forum.
Fitting Central Pick Up pipe
You have to remove the large retainer plate at the pinion end of the gearbox then remove the locking plate (just slide out) and remove the layshaft and laygear, being careful not to drop the two thrust washers and any bearings that are within the laygear... the laygear and CPU have to be put together to fit wihin the case, its a little juggling act but not too difficult.
CPU = Central Pick Up pipe
Final stopper stage
Dolphin glaze as a stopper / top filler http://www.ebay.co.uk/sch/i.html?_nkw=U-pol+dolphin+glaze&_sacat=0&_odkw=dolphin+glaze&_osacat=0&_from=R40
Also been discussing how to overcome this little gap where I had an A panel fitted by a garage.

Going to strip the subframe down again tonight so its a bit lighter when I'm trying the fit of the new heel board sections.
