Hi Guys, I'm after a little bit of help removing a rear brake drum on a 1983 110. Drum is spinning freely and not stuck on the shoes and the retaining screw out so I'm assuming it's stuck on the plate beneath. I've tried whacking it with a hammer on the face but no luck. Does any body know what size the threaded hole is that pushes it off the plate? I've seen on here someone thinks it 5/16unc but that seems a little small. The hole will take an 8mm bolt quite easily, so looking at something around 9 - 9.5mm. So before I order anything are there any suggestions from you lot? Thanks
