Job done, so I thought I'd mention a few things that might help someone else with the same task: - to draw off the rear flange, the propshaft is in the way. It will not drop low enough due to the chassis. By removing the rear gearbox mounting bolts and the top 3 bellhousing studs (to just clear the bulkhead) the rear of the box can be jacked up high enough to tap the flange off. - an old, cut down clutch release brg carrier is just the right o/d, with a large washer and the flange nut
