Series gearbox, or just back plate/gear (to remove overdrive) in Essex wanted

Hi guys,

My series 3 has had it's overdrive removed. Does anyone have parts for sale to make my gearbox work again?
Or maybe a complete gearbox if unwilling to split, and it's cheap? the rest of it can be knackered!

I'm near Chelmsford in Essex if anyone has anything within reasonable distance..
Thanks very much!

I have but it'll have to be plus cost of parcel-force. I'm not faffing around with couriers

I'll have the crown nut and tab washer somewhere anorl
