A big push today, carpeting the drivers side of the cabin and putting everything back together. Just waiting in a voltage stabiliser and some star washers for fixing the Commer letters. I have sourced a weld on filler neck and lockable petrol cap. Then it’s MOT time. All systems, electrics and mechanicals are GO!
There are two sizes of front cylinders, later vans have a larger bore. The rear cylinders are the same all though apart from the Series and PA models having a lever for the hand brake. I do seem to remember there were two sizes of rear drum as well cant remember the diameters but I would think they would only get bigger as the van models were updated so yours would be the larger type. A tape measure would take the guess work out of it
