Rb5 wishbone hangers?

[Rebelrc]

Can anyone tell me the part numbers for the Ali replacement rear wishbone hangers/ mounts ( forward and back) for the rb5sp2
I am on the plastic kit items , cannot find my manual and don't want to order the wrong ones as I hear they are quite expensive
Also I'm a little confused as hasn't the rb5 got lots of different length wishboes and mounts etc?
Many thanks
