Hey guys, I've got a 1992 Subaru Brumby EA81 which I love. I recently replaced the front CVs and noticed that the cone washer (sits behind the axel nut and spring washer) is really badly worn out. This results in the axel nut coming loose every so often which is a real pain. Does anyone know where I can find these washers to replace? I can't find them anywhere online. Also where can I find a couple of rear CVs for the Brumby? Then need replacing too but they seem really hard to track down... Thanks for your help :)
