Hyper parts question
 

Hi all,
I currently have a Hyper 8.5 all going well but I have no spares for it. I have access to a very cheap hyper 7 roller. Can anyone tell me what parts off the hyper 7 will be of any use in the 8.5? just so I know if its worth getting it posted down to me.... I would assume diff and gearbox internals would be the same but am wondering about things like front and rear arms etc...
thanks in advance

About the only thing that interchanges is the gearbox and diff and that's it.
