Few rb questions

[Empire087]

So i recently picked up a drop in rb20 swap, motor was shown nice and healthy being run and everything before it was pulled. Well i was told the trans had some trouble shifting into 1/2 and figured it needed a new set of syncros. Well upon pulling it apart i found that one of the shift arms is broken and one of the smaller gears(Not syncro) are broken in multiple pieces. Is this trans pretty much a paperweight at this point? Also the motor did not come with power steering as it was deleted as soon as the PO bought it. I read that you can use the ka24de hicas pump, would i need to use the power steering bracket from the rb aswell? Or can i use the ka one? What are my options for power steering?

Thanks for the help,
Dakota
