Thanks Degsy, couldnt find me Brumagem so went for the Royal Corps "Tool, fine adjusting" instead. Had to drop the Diff, which was a first for me, but after a quick Telcon with an informed mate, Seems to have come out OK. Housing and gears in good nick, no knackered teeth or floaty metal bits, which is a good thing right ?
Net result
1 times Halfshaft U/S
1 times lovely cog wheely thing
1 times cog wheely thing holder thing red and black tape also on brackets and bearing covers to avoid swapsy issues (another 3rd party top tip there)
quite chuffed with meself, I could get into this restoration lark :-).
Another question, any reccomends for tyre suppliers ? I seen some on e-bay for £70 or £79 for Landy ones that look a bit more road worthy than the bar ones blokey reckons they will fit a Willysish wheel.
