Since I discovered the factory put the LH thread nut and stub shaft on drivers side rear hub and RH thread nut and stub shaft on passenger side rear hub, I have been trying to swap them around, but I can't find any suitable nuts given the Westfield parts shop is no more. I believe they are M22 1.5 nyloc nuts with 41 mm AF , does anybody know where you can get them ? Febi produce what they say is suitable for all sierra's but it says they are M27 2 41 AF clearly that diameter is too big. Kit car direct etc don't have any Sierra M22 in stock , is there any other supplier out there who might have them ?
