<VV> Reverse idler gear for 1964 4-speed

[clynn66 at bigpond.net.au]

I wonder if anybody has a reverse idler gear for a 1964 4-speed gearbox or if they know where I might be able to get one. Prefer new but would consider a good used one. I am doing a gearbox rebuild. Mine has one chipped tooth and while I could get away with it I would prefer to replace when doing the rebuild. It didn't jump out of gear prior to dismantling. Clarks are out of stock. Any help appreciated. Colin LYNN # 028299 Perth Western Australia.
