T4 California side mirror repair

[Hubble]

Driver side mirror is now hanging loosely. One of the metal rods that connects to the upper spring has snapped. Does anyone know if these are replaceable? I know I can get a replacement unit but £65 and plus it would need to be painted etc.
Part number and/or diagram would be great.
Thanks

I got a pair of heated electric ones from Brickwerks for about £70, so assuming half that each. Wasn't worth the trouble of trying to replace the old ones.

Ok thanks. Might do that but if I could just get the part i could keep it all original.
