E27N steering arms, row crop type wanted

[1962 model]

Can anyone please tell me where I can get new E27N steering arms.
I have fitted my E27N Malcolm Moor loader with a row crop axle from a E1A, but I need steering arms to suit, or my steering is going to be rather heavy. I do have the steering arm extension from the loader which will make the E1A arm a bit longer, but still likely to be too short.
Anny helpful suggestions appreciated, Mike
