G'day
I have some information on the McNamara Diff Lock system. It includes a sales receipt for $425 for the supply of one only diff strengthening kit (Series 2) complete with axles and drive flanges dated 21/12/81. There is also the operating instructions and an article from 'Bushdriver' magazine. The article lists the price of the kit for the series 3 as $257. I can scan them if anyone is interested.
Cheers Hugh
